Answer:
202 cm^2
Step-by-step explanation:
SA = 2LW + 2LH + 2WH
SA = 2(4 cm)(5 cm) + 2(4 cm)(9 cm) + 2(5 cm)(9 cm)
SA = 40 cm^2 + 72 cm^2 + 90 cm^2
SA = 202 cm^2
Answer:
785.4cm^3
Step-by-step explanation:
(10÷2)^2*π=25π
25π*10=250π≈785.4
1. The simplified expression is 10x+8y-12.
Combine like terms to simplify the expression.
-6x-12+8y+16x
-6x and 16x are both like terms, so those can be combined.
-6x+16x=10x
10x+8y-12
2. The solution to the equation is x=13.
Solve by adding 17 to both sides of the equation.
-4=-17+x
-4+17=-17+17+x
13=x
