Answer:
164 in^2
Step-by-step explanation:
length = 10 in
breadth = 3 in
height = 4 in
surface area = 2(lb + bh + hl)
=2(10*3 + 3*4 + 4*10)
=2(30 + 12 + 40)
=2*82
=164 in.^2
Answer:
x = -1
y = -5
Step-by-step explanation:
y = x - 4 y = x - 4
2x + 3y = -17 y = (-1) - 4
2x + 3(x - 4) = -17 y = -1 - 4
2x + 3x - 12 = -17 y = -5
5x - 12 = -17
5x - 12 + 12 = -17 + 12 <u>Check</u>
5x = -5 2x + 3y = -17
5x/5 = -5/5 2(-1) + 3(-5) = -17
x = -1 -2 + -15 = -17
-17 = -17
I am pretty sure that it is B
