Anyone pzzz answer this giving brainlist and 50 points for correct answer

Nuetrik [128]

Answer:

see below

Step-by-step explanation:

12x+24x+18 = 36x+24-6

Combine like terms

36x+18 = 36x+18

Subtract 36x from each side

36x+18-36x = 36x+18-36x

18 = 18

This is always true, so the equation is true for all values of x

Solve the equation or formula for the indicated variable.

8090 [49]

Answer:

h = $\frac{T - 2\pi r^{2}}{2\pi r}$

Step-by-step explanation:

T= 2rπh + 2πr²

Subtract terms that don't include the indicated variable from both sides:

T= 2rπh + 2πr² ⇒ T - 2πr² = 2rπh

Divide values being multiplied by indicated variable from both sides:

T - 2πr² = 2rπh ⇒ $\frac{T - 2\pi r^{2}}{2\pi r}$ = h

If f(x) = 2x2 + 5x - 8 and f(x) = -10, which of the following could be a value for x? -2

alexdok [17]

Answer:

x = -2 or x = -1/2

Step-by-step explanation:

We can just set up an equation where the quadratic is equal to -10, and then solve the equation:

$2x^2+5x-8=-10\\2x^2+5x+2=0\\\\$

Now, factor:

$(2x+1)(x+2) = 0\\x=-2 \text{ or } x=-1/2$
