Answer:
About 34 workers
Step-by-step explanation:
200/30 to find on average how many trees can be carved by one worker
The answer is 6.666, so just 6
Then 6*4=24 to figure out how many more trees can be carved by (4 more) workers
So, add 4 to 30 and about 224 trees can be carved.
Combine like terms to get 2y2-2y+4x
Answer:
x=1,-5x=1,−5
Step-by-step explanation:
0=(x−1)(x+5)
2 Switch sides.
(x-1)(x+5)=0(x−1)(x+5)=0
3 Solve for xx.
x=1,-5x=1,−5
8x^2 -3 = 2
add 3 to each side
8x^2 = 5
divide by 8
x^2 =5/8
take the square root of each side
x = +- sqrt (5/8)
Pythagorean theorem: a^2 + b^2 = c^2
36^2 + b^2 = 85^2
1296 + b^2 = 7225
b^2 = 7225 - 1296
b^2 = 5926
b = square root of 5929
b = 77 inches long
