Answer:
The answer is : 23.25 in ²
Step-by-step explanation:
There are 3 triangles with the same lengths: height = 5in and base = 5 in
There is one triangle: height = 4.3 in base = 5 in
Formula
Area = height x base / 2
For the triangles
Area = 5 in x 5 in /2 = 25 /2 = 12.5 in²
For the triangle
Area = 4.3 x 5 /2 = 21.5 /2 = 10.75 in²
Total surface area = 12.5 + 10.75 = 23.25 in²
Answer:
28 m
Step-by-step explanation:
full roll length: r
Ryan bought: r/4
He trimmed 2 m: r/4 - 2

r/4 = 7
r = 28
Answer: 28 m
Answer:
6n +7
Step-by-step explanation:
You cannot solve since this is an expression, you can only simplify
-2(-3-3n)+1
Distribute the -2
-2*-3 -2*-3n +1
6 +6n +1
Combine like terms
6n +7
