The answer is 80. This is because we can find the area of one of the triangles by (4*8)/2 = 16. We multiply this by 4 since there are 4 triangles. 16*4 = 64. Now finally, we add the area of the base to this value. 4*4+64=80. Therefore the answer is 80 cm^2

<u>Given expression is </u>

And since you can’t just buy half a pizza it would have to be 23 pizzas :)
Answer:
x = 7
Step-by-step explanation:
3x - 9 = 12
3x = 12 + 9
3x = 21
x = 21 ÷ 3
x = 7
3×6/8 reduce is 3× 3/4= 3/1×3/4=9/4 or 2 1/4
