X + 4 = 4x + 2
let’s put the x’s on one side and the numbers on the other
(whatever you do to one side, you have to do to the other)
x + 4 = 4x + 2
- 4 - 4x
x - 4x = 2 - 4
-3x = -2
—— ——
-3 -3
x = 2/3
to check this, we can put 2/3 in for x
(2/3) + 4 = 4(2/3) + 2
4 2/3 = 8/3 + 2
4 2/3 = 2 2/3 + 2
and there we can see both sides equal 4 and 2/3, making it true
Answer:
tanθ = ![\frac{8}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B15%7D)
Step-by-step explanation:
By applying tangent rule in the given right triangle ROE,
tanθ = ![\frac{\text{Opposite side}}{\text{Adjacent side}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BOpposite%20side%7D%7D%7B%5Ctext%7BAdjacent%20side%7D%7D)
tanθ = ![\frac{RO}{OE}](https://tex.z-dn.net/?f=%5Cfrac%7BRO%7D%7BOE%7D)
tanθ = ![\frac{8}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B15%7D)
Therefore, answer will be tanθ = ![\frac{8}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B15%7D)
Answer:
To find the product, we use FOIL method.
First terms
Outer terms
Inner terms
Last terms
Product = (7x * 8x) + (7x * 5) + (-4 * 8x) + (-4 * 5) =
Product = 56x2 + 35x - 32x - 20 =
Product = 56x2 + 3x - 20

Answer
D
step 1
Memorize the formula, or look at the formula and solve it.
Answer:
x=14
Step-by-step explanation:
g(x) = 2(x − 4)
Let g(x) = 20
20 = 2(x − 4)
Divide each side by 2
20/2 = 2(x-4)/2
10 = x-4
Add 4 to each side
10+4 = x-4+4
14 =x
