The answer is 4,000. if she can run 2,000 feet in 4 minutes, multiply both by two and the answer is 4,000 feet in 8 minutes
Answer:
6, -4
Step-by-step explanation:
abs(-1+x)=5
-1+x=5 and -1+x=-5
-------------------------
-1+x=5
x=5-(-1)=5+1=6
-------------------
-1+x=-5
x=-5-(-1)=-5+1=-4

Answer:
B
Step-by-step explanation:
Given:
Net of a triangular prism
To find:
Which equation can be used to calculate the surface area of the triangular prism.
Solution:
Using formulas:
Area of rectangle = length × width
Area of triangle = 
Area of left triangle = 
Area of right triangle = 
Area of bottom = 5 × 10
Area of Middle = 12 × 10
Area of top = 13 × 10
Surface area of triangular prism:
Surface area = Area of left triangle + Area of right triangle + Area of bottom + Area of middle + Area of top

Replace multiplication by brackets.

The equation can be used to calculate surface area of triangular prism is
.
