If it takes eight men ten hours, it would take seven men nine hours, six men eight hours, five men seven hours and that brings us to the answer you need. It would take four men six hours.
Answer:
It will be A because of if you round it it would be -7
4(9) + 3s = 75
36 + 3s = 75
3s = 39
s = 13
Answer:
D
Step-by-step explanation:
-4(-2)^2 -3(-2) +2
-4(4) +6+2
-16+8
-8
Step One
Solve for CE as a numerical value
CE = 1/2 * CD = 1/2 66 = 33
CE = 33
Step Two
Solve for x
CD also equals x^2 - 3 which is given.
x^2 - 3 = 33 Add 3 to both sides
x^2 = 33 + 3
x^2 = 36 Take the square root of both sides
sqrt(x^2) = sqrt(36)
x = 6
Step 3
Find the length of AE
AE is given as 6x - 10
x = 6
AE = 6*6 - 10
AE = 36 - 10
AE = 26
Step 4
Find AB
AE = 1/2 AB Definition of bisect
26 = 1/2 AB Multiply by 2
2*26 = AB
AB = 52 <<<<<<<<Answer
