What is equivalent to<br>x2+ 14x = -13​
postnew [5]

Answer:

X= 1 AND 13

Step-by-step explanation:

x2+14x = -13

by completing the square method

you add the square of half the coefficient of b to both sides

which is (14/2)^2

x^2+14x+(7^2) = -13 +(7^2)

x^2 + 7^2 = -13 + 49

x^2 + 7^2 = 36

(x + 7)^2 = 36

find the square root of both sides

(x+7) = + or - 6

x=7-6 ; 1

or

x= 7+6 ; 13

If q/18 = 5 what does q = to
qaws [65]

Answer:

Q= 90

Step-by-step explanation:

To do this problem you need to get q by itself and to do that you would move the 18 over

When you move the 18 over however you need to multiply and you will get 90

When ever you want to get a variable by itself always remember to switch the sign so if it was positive then switch it to negative and vice versa. It will also apply to multiplication and division just like this one
