I don't know how to solve this. How would I solve this? Thanks!!!!

Afina-wow [57]

Answer:

x = 11 units

Step-by-step explanation:

Area of triangle = (base + base 2) * h *1/2

so (7 + x )* 7 * 1/2 = 63

63 x 2 = 126

126 / 7 = 18

18-7 = x

x = 11

Check

(7+11)* 7 * 1/2

18* 7 = 126

126 x 0.5 = 63

CORRECT!

(p.s., tell me if wrong :P)

What shows the correct substitution of the values a,b, and c from the equation 0=-3x^2-2x+6

Arlecino [84]

When dealing with a quadratic equation, you usually assign the following name to the coefficients of the variables:

$ax^2+bx+c=0$

So, $a$ is the coefficient of $x^2$ , $b$ is the coefficient of $x$ and $c$ is the constant term.

In your case, the coefficient of $x^2$ is -3, so $a=-3$

The coefficient of $x$ is -2, so $b = -2$

The constant term is 6, so $c = 6$
