Answer:
-21
Step-by-step explanation:
<h3>
Answer: 21.4 square meters</h3>
Work Shown:
A = area of the front triangular face
A = base*height/2
A = 2*1.7/2
A = 1.7
L = lateral area
L = (perimeter of the base)*(depth)
L = (2+2+2)*(3)
L = 18
SA = total surface area of a triangular prism
SA = 2*A+L
SA = 2*1.7+18
SA = 21.4 square meters
456÷100=4.56
How to check your work: 456÷4.56=100
Answer:
Answer: =2a + 16
Step-by-step explanation:
8+9−1+2a =8+9+−1+2a
now its time to to do CLT
=8+9+−1+2a
=(2a)+(8+9+−1)
=2a+16
