Answer:
A has the largest surface area.
Step-by-step explanation:
Surface Area of A = 2(10*3.5) + 2(10*4) + 2(4*3.5)
= 70 + 80 + 28
= 178 in^2.
For B:
Area = 2(12*3.2) + 2(12*2.8) + 2(2.8*3.2)
= 76.8 + 67.2 + 17.92
= 161.92 in^2.
Answer:
X=5
X=2
Step-by-step explanation:
X^2-9=0 add 9 to both sides
x^2=9 take the square root of both sides
x=±3
