Answer:
Step-by-step explanation:
2(3x−5)+4x−10=4x+2(x+6)
Step 1: Simplify both sides of the equation.
2(3x−5)+4x−10=4x+2(x+6)
(2)(3x)+(2)(−5)+4x+−10=4x+(2)(x)+(2)(6)(Distribute)
6x+−10+4x+−10=4x+2x+12
(6x+4x)+(−10+−10)=(4x+2x)+(12)(Combine Like Terms)
10x+−20=6x+12
10x−20=6x+12
Step 2: Subtract 6x from both sides.
10x−20−6x=6x+12−6x
4x−20=12
Step 3: Add 20 to both sides.
4x−20+20=12+20
4x=32
Step 4: Divide both sides by 4.
4x/4 =32/4
x=8
Answer:
Option D. 5890.5 feet²
Step-by-step explanation:
An individual head of a sprinkler system covers a circular are of grass with a radius of 25 feet.
Yard has three sprinkler heads that each cover circular area with no overlap.
We have to calculate the approximate area watered by these 3 sprinkler heads.
Area covered by one sprinkler = π×r² = π×(25)² = 625π feet²
Therefore area covered by three sprinkler heads = 3 × 625π = 5892.85 feet²
which matches the approximate value of Option D. 5890.5 feet²
