Answer:
Step-by-step explanation:
There are four 8s, so s should represent one 8.
The 12 is made up of 4 * 3, so B should be the answer.
Answer: B or 4(s + 3)
When the brackets are removed, you get 4s + 12
Answer:
b-13
Step-by-step explanation:
I'm pretty sure this is right? Unless I'm missing something, if I am I am terribly sorry.
KH = 3(x + 2) + <span>3x - 4
KH = 3x + 6 + 3x - 4
KH = 6x + 2 = 44
6x = 42
x = 7
HJ = 3(x + 2)
HJ = 3(7 + 2)
HJ = 27</span>
Answer:
Perimeter: 60.6cm
Area: 212.3cm
Step-by-step explanation:
When calulating the perimeter, you are adding the length of all the sides together. Since the figure is a rectangle, two two pairs of sides will be different lengths. Solving is as follows:
P= 11+11+19.3+19.3 or P=11(2)+19.3(2) =60.6
With area, you need the total amount of mass, so you would multiply two sides. In this case, the two are 11cm and 19.3cm.
A= 11(19.3)cm =212.3
Answer:
- 5x²-2x+7+2x²+6x-9
- 5x²+2x²-2x+6x+7-9
- 7x²+4x-2
so, 7x²+4x-2 is yr answer.
hope it helps.
