Answer:
x = 4 or x = -4 is your answer
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.
<h2><u>ANSWER </u></h2>
x= 3
Step-by-step explanation:
=> -4x – 5 + 2x = -11
=> -2x = -11+5
=> -2x = -6
=> x= 6/2
=> x= 3
A similar because all triangles add up to 180 ,
they both have 80 so leaves 100 degrees left..
and they both have the same #'s 80, 60, & 40 degrees equal to 180 degrees
