R^2+6r-40 factor each expression
bearhunter [10]
(r + 10)(r - 4)

To double check:
r * r is r^2

10 * r = 10r; -4 * r = -4r
Combine to get 6r.

-4 * 10 = -40

erastova [34]
The solutions to system of equations are the point of intersection of the graphs of the equations.
The point of intersection of the graphs of the given equation is (0, 2). Therefore, point (1, 1) is not a solution to the system of equation.

Help!!!<br> Slove for x.<br> A.11<br> B.9<br> C.13<br> D.14
olga nikolaevna [1]

Answer:

Step-by-step explanation:

The secants form a proportion where the full length of the secant is the denominator of a fraction where the numerator is the external part of the secant.

7/(x + 7) = 6/(15 + 6)         Cross Multiply after combining

7 / (x + 7) = 6/(21)                

6 * (x + 7) = 7 * 21             Remove the brackets

6x + 42 = 147                   Subtract 42

6x = 147 - 42

6x = 105                           Divide by 6

x = 17.5

I think I've done this correctly. If you find an error, please let me know and I'll open it for editing.
