Answer:
total area = 530 ft^2
Step-by-step explanation:
bottom = 8 x 25 = 200 ft^2
2 sides = 8 x 5 x 2 = 80 ft^2
2 other sides = 25 x 5 x 2 = 250 ft^2
200 + 80 + 250 = 530 ft ^2
The first equation ;-)
It simplifies down to 3 = -5 which isn't true so, no solutions!
Answer:
The value of the equation for x is .
Step-by-step explanation:
Consider the provided equation.
We need to solve the equation for x.
Distributive property:
Use the distributive property and solve the above equation.
Add ax and 8 to both the sides.
Simplify the equation.
Take x common.
Now divide both the sides by b+a.
Hence, the value of the equation for x is .
Answer:
106 cm²
Step-by-step explanation:
the surface area is the sum of the areas of the faces of the prism
area of 2 rectangles (left/ right ) = 2 × 7 × 5 = 70 cm²
area of central rectangle = 3 × 7 = 21 cm²
area of 2 congruent triangles = 2 × × 3 × 5 = 3 × 5 = 15 cm²
surface area = 70 + 21 + 15 = 106 cm²
