Answer:
S = 40 square inches
Step-by-step explanation:
Surface area = area of base + area of lateral faces
Area of the base (square):
A = lw
A = 4(4)
A = 16
Area of lateral faces (triangle and there are 4 of them):
A = bh/2
A = 3(4)/2
A = 12/2
A = 6
Since there are 4 lateral faces, multiply the area by 4.
6 x 4 = 24
Surface area = 16 + 24
S = 40 square inches
Answer:
Step-by-step explanation:
4/(2+4+8+2) = 4/16 = 1/4
For each value of n your going to plug that number back into the original equation.
8. square root of (1)^2 +1 which will give you 2.
9. square root of (4)^2 +4 which will give you 8.
10. square root of (16)^2 +16 which will give you 33.
Answer:
Step-by-step explanation:
Cross multiply and get:
L = 5w
L = 5w/
W = L/5
Answer:
8
Step-by-step explanation:
-6 + 6n = 42
First move the 6 over to the other side by adding....
6n = 48
now you will divide by 6 to get n by itself
n = 8
