Answer:
(2x - 5) • (x + 3)
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 2 • -15 = -30
Step-2 : Find two factors of -30 whose sum equals the coefficient of the middle term, which is 1 .
-30 + 1 = -29
-15 + 2 = -13
-10 + 3 = -7
-6 + 5 = -1
-5 + 6 = 1 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -5 and 6
2x2 - 5x + 6x - 15
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (2x-5)
Add up the last 2 terms, pulling out common factors :
3 • (2x-5)
Step-5 : Add up the four terms of step 4 :
(x+3) • (2x-5)
Which is the desired factorization
Final result :
(2x - 5) • (x + 3)
A force of 182.6 lb should be applied to lift 700 lb object.
<h3>How to calculate the force?</h3>
Let the force required to lift be F
Total length = 29 in.
Distance of short end from pivot = in.
Distance from long end = 29-6 = 23 in.
Now Equating moments
F × 23 = 700x6
23F = 4200
F = 4200/23
= 182.6 lb
A force of 182.6 lb should be applied to lift 700 lb object.

Answer:
we have x = -62 or x = 66
Step-by-step explanation:
16=(x-2)^2/3
I would take square root first
4 = (x - 2)^ (1/3)
or -4 = (x - 2)^(1/3)
.....
4^3 = x - 2
64 = x - 2
x = 66
or -4 ^3 = x - 2
-64 = x - 2
x = -62
we have x = -62 or x = 66
Answer:
The answer to your question is: letter C
Step-by-step explanation:
4x² + 5x - 6
Process
4 x - 6 = - 24
Find two numbers that added gives + 5 and multiply gives -24
These numbers are + 8 and - 3
4x² + 8x - 3x - 6
4x ( x + 2) - 3(x + 2)
(x + 2) (4x - 3)
