Answer: 55 Square inches
Step-by-step explanation:
You should find the area of the square and rectangle separately
To find the area you multiply length times width, so the area of the square is 4×4 which equals 16
Then you do the same to the rectangle, 13×3=39
To find the area of the whole figure you add the area of the two shapes together 16+39 which should give you 55
Answer:
When x = -1, f(x) = 2
Step-by-step explanation:
f(x) = (1/2)^x
When x = -4
f(x) = (1/2)^x
f(x) = (1/2)^-4
= 1 ÷ (1/2)^⁴
= 1 ÷ 1^⁴/2^⁴
= 1 ÷ 1/16
= 1 × 16/1
= 16
When x = -1
f(x) = (1/2)^x
= (1/2)^-1
= 1 ÷ 1/2^1
= 1 ÷ 1/2
= 1 × 2/1
= 1 × 2
= 2
When x = -1, f(x) = 2
