Using the equation 3(2x + 8) = 4x + 10, I found out that x is equal to -7.
The steps I took:

3(2x + 8) = 4x + 10 - Written out equation
6x + 24 = 4x + 10 - Distributive property on the left
2x + 24 = 10 - Subtracted 4x from both sides
2x = -14 - Subtraced 24 from both sides
x = -7 - Divided by 2

Use the factor theorem to determine whether the first polynomial is a factor of the second polynomial
Diano4ka-milaya [45]

Answer:

not a factor

Step-by-step explanation:

If (x - 3) is a factor then f(3) = 0

f(x) = 2x² - 4x + 30

f(3) = 2(3)² - 4(3) + 30 = 18 - 12 + 30 = 36 ≠ 0

Since f(3) ≠ 0 then (x - 3) is not a factor of f(x)

Elanso [62]

Answer:

3.5

Step-by-step explanation:

This can be calculatdd by applyinthe g Pythagorean theorem

a^2 + b^2= c^2

12^2 + x^2= 12.5^2

144+ x^2= 156.25

x^2= 156.25-144

x^2= 12.25

x= √12.25

x= 3.5

Hence the distance between the ladder and the house is 3.5 ft
