I'll guess P is the perimeter, the sum of the edge lengths.
In centimeters
I get 4 + 4 + 4 + 4 for the sides of the isoscles triangles
5 + 5 + 2.8 + 2.8 for the rectangular base
5 for the apex/top
P = 4+4+4+4+5+5+2.8+2.8+5=36.6 cm
Not sure why the exact answer isn't there, but first choice seem best.

Get equivalent expression using completing the square
<em>Follow these steps:</em>
- <em>Take the coefficient of y; That is -12</em>
- <em>Divide it by 2; That is (-12/2)</em>
- <em>Square it: (-12/2)^2</em>

Factorize:
Answer:
7(3a + 5)
Step-by-step explanation:
Rewrite 21 as 7 · 3
Rewrite 35 as 7 · 5
Therefore,
⇒ 21a + 35 = 7 · 3a + 7 · 5
Factor out common term 7:
⇒ 7 · 3a + 7 · 5 = 7(3a + 5)
