I assume you want to find the value of w
The first thing we will do is divide both sides by 0.25
4/0.25 = 0.25(w - 4.3)/0.25
The two 0.25s cancel each other. 4/0.25 = 16
16 = w - 4.3
Now we add 4.3 to both sides
16 + 4.3 = w - 4.3 + 4.3
The two 4.3s cancel each other 16 + 4.3 = 20.3
20.3 = w
w = 20.3
Convert the 5 6/8 into a fraction
46/8
3/8+46/8=49/8
or
6 1/8
Answer:
2x² + 5x - 3
Step-by-step explanation:
(x + 3)(2x - 1)
Use FOIL
First terms
x * 2x = 2x²
Outer terms
x * -1 = -x
Inner terms
3 * 2x = 6x
Last terms
3 * -1 = -3
---------------------
FOIL
2x² - x + 6x - 3
Combine like terms
2x² + 5x - 3
