Answer:
It is (a + b)(b + c)
Step-by-step explanation:
[tex]ab + bc + {b}^{2} + ac[/tex]
arrange the function:
[tex] = (ab + ac) + ( {b}^{2} + bc)[/tex]
factorise out common terms [ a and b ]:
[tex] = a(b + c) + b(b + c)[/tex]
form a bracket of factors:
[tex] = (a + b)(b + c)[/tex]
if length of each side of square is 7 m find it's area and perimeter
Answer:
Area is 49 m²
Step-by-step explanation:
[tex]area = (side \times side)[/tex]
since all sides are equal, side = 7 m
[tex]a = (7 \times 7) \: {m}^{2} \\ a = 49 \: {m}^{2} [/tex]

A polygon which is regular has interior angles measuring 150°. This polygon is called a:
Answer:
Step-by-step explanation:
equilateral triangle
Answer:
Dodecagon (12 - sided polygon)Step-by-step explanation:
Let it be n- sided polygon.
Sum of interior angles is 150n.
On the other hand we know the sum of interior angles of a regular n - sided polygon is calculated using the following formula:
S = 180(n - 2)Compare the sums and solve for n:
180(n - 2) = 150n180n - 360 = 150n180n - 150n = 36030n = 360n = 360/30n = 1212-sided polygon is called dodecagon

Answer:
a) y = [tex]\frac{1}{2} x[/tex]
b) y = [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
I. If y = 9 and x = 18
so x is double value of y or y * 2
y will be half of x value
that makes y = [tex]\frac{1}{2}[/tex] x
II. If x = 5, replace x with 5
y = [tex]\frac{1}{2}[/tex] (5)
y = [tex]\frac{5}{2}[/tex]
Answer:
(a).
[tex]{ \boxed{ \sf{y = \frac{1}{2}x }}}[/tex]
b).
[tex]{ \boxed { \sf{y = \frac{5}{2} }}}[/tex]
Step-by-step explanation:
explanation for (a):
[tex]{ \sf{y \: \alpha \: x}} \\ { \sf{y = kx}} [/tex]
when y is 9, x is 18
[tex]{ \sf{9 = (k \times 18)}} \\ { \sf{k = \frac{1}{2} }}[/tex]
therefore equation is:
[tex]{ \sf{y = \frac{1}{2}x }}[/tex]
explanation for (b):
when x is 5:
[tex]{ \sf{y = \frac{1}{2}x }} \\ \\ { \sf{y = \frac{1}{2} \times 5}} \\ \\ { \sf{y = \frac{5}{2} }}[/tex]
10-7X-5+12x=0
Explain
Answer:
x = -1
Step-by-step explanation:
[tex]10 - 7x - 5 + 12x = 0[/tex]
➡️ [tex]5 - 7x + 12x = 0[/tex]
➡️ [tex]5 + 5x = 0[/tex]
➡️ [tex]5 + 5x - 5 = 0 - 5[/tex]
➡️ [tex]5x = 0 - 5[/tex]
➡️ [tex]5x = - 5[/tex]
➡️ [tex]5x \div 5 = - 5 \div 5[/tex]
➡️ [tex]x = - 5 \div 5[/tex]

Answer:
2n + 11
Step-by-step explanation:
2(1) + 11 = 13
2(2) + 11 = 15
2(3) + 11 = 17
the 2 is the constant difference between the first 2 terms.
the numbers in brackets are the term number.
you have to multiply the difference with the term number.
then you will have to take that answer and subtract it from the first term number.

Answer:
The length is from -5 to +7, so the length answer is 12, The midpoint would be that divided by 2, so six.
Step-by-step explanation:
Answer:
Length = 12
Midpoint = 1
Step-by-step explanation:
to find the length u cancount from left to right of the segment and u can see that it is 12 units long. To find the mid point just take half of the the length, which is 6, and count that many units from either side of the segment. you'll stop at 1 do that is the mid point of the graph.

Which equation is equivalent to the given equation? x^2 - 10x = 14
Answer:
(x - 5)² = 39
Step-by-step explanation:
Given
x² - 10x = 14
To obtain an equivalent equation use the method of completing the square.
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 5)x + 25 = 14 + 25
(x - 5)² = 39
I believe that the answer you are looking for is (x-5)²-39, if you use the completing the square method.
Solution:
x²-10x=14
Transferring 14 from the right side to the left side,
x²-10-14=0
Squaring the equation,
(x-5)²-39, or (x-5)²=39 (Depends on how you prefer to write it).
So, that is the final answer. I hope this helped. If you have any questions about the answer, please let me know. Enjoy your day and take care!

Convert 402.12 to a fraction
Answer:
40212/100
Step-by-step explanation:
To write 402.12 as a fraction you have to write 402.12 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
402.12 = 402.12/1 = 4021.2/10 = 40212/100
And finally we have:
402.12 as a fraction equals 40212/100
answer:
[tex]\frac{10053}{25}[/tex]
first, you would convert 402.12 to a mixed number by placing the numbers to the right of the decimal over 100. and then reduce the fraction.
you would get [tex]402\frac{3}{25}[/tex]
convert the mixed number to an improper fraction:
25×402+3=10053
and lastly, place your new numerator over the original denominator:
[tex]\frac{10053}{25}[/tex]

16 The cost for parking at a city airport is shown in the table.
Price for first day
$16.60
For every
2
day afterwards
$9
Yuri pays $124.60 to park his car.
How many days does he park his car for?
Show your working.
Answer:
He paid $9 twelve times
12× 2= 24 days
Step-by-step explanation:
1st day = $16.60
3rd day=$ 9 (i.e for every 2days afterwards)
5th day=$ 9
Yuri pays : 124.60
124.60-16.60
= $108.00
After paying the first day he paid 108.00
108.00÷ 9 = 12
He paid $9 twelve times
12× 2= 24 days
What is the value of X?
Answer:
5 * sqrt(3)
Step-by-step explanation:
The sine of 60 degrees is equal to x/10 because x is opposite to it and 10 is the hypotenuse. Since the sine of 60 degrees is equal to sqrt(3)/2, sqrt(3)/2 = x/10. Because 5sqrt(3)/10 = sqrt(3)/2, 5sqrt(3)/10 = x/10 and therefore 5sqrt(3) = x.

Compare negative square root of 7 and -3.12345
Answer: Square root of negative 7 is greater than -3.12345
Step-by-step explanation: Since the square root of -7= 2.64575131 i (A positive number) Then it's greater, since the positive number is always greater than the negative numbers, because the negative numbers are further below zero than the positive number, if there is a number below the zero and a number above the zero, the one above the zero is greater, because it's a positive number, the one below 0 is negative.
