<span>2w - 5(w+1) = 3w + 1
The first step here is to distribute the -5 to everything inside the parentheses.
</span><span>2w - 5w - 5 = 3w + 1
Now combine like terms on the left side.
-3w - 5 = 3w + 1
Add 3 to both sides.
-5 = 6w + 1
Subtract 1 from both sides.
-6 = 6w
Divide both sides by 6.
-1 = w
So the answer is:
w = -1</span>
The surface area is 803.84ft<span> ². and formula A is the correct formula for finding the surface area of a sphere.</span>
It’s 10077 because it’s hey
Answer:
162m²
Step-by-step explanation:
distance from corner to center = 1/2 of the diagonal
all sides are equal, and this has 4 sides, so it is a square
9m = 1/2 of diagonal
multiply both sides by 2 to isolate the diagonal
18m = diagonal
area of square = length²
length * √2 = diagonal
given the diagonal, we can find the length and then the area
length * √2 = diagonal
divide both sides by √2 to find the length
18m/√2 = length ≈12.7
square the length to find the area
area = 162 m²
Step-by-step explanation:
I'm not sure what the square root method is, but I'm assuming that you factor.
This is how I would solve it:
Since time can't be negative, you rule out the -3/2.
