12 added to the square of a number is equal to 11 times the number,
minus 18. What is the number? (There are two solutions.)
a. 12 + x = 11x − 18, 3 or 5 c. 7 + x2 = 7x − 5, 4 or 5
b. 7 + x2 = 7x − 5, 6 or 7 d. 12 + x2 = 11x − 18, 5 or 6

d. 12 + x^2 = 11x - 18, 5 or 6

Step-by-step explanation:

Let the number be x

12 + x^2 = 11x - 18

Rearrange the equation

x^2 + 12 - 11x + 18 = 0

x^2 - 11x + 12 + 18 = 0

x^2 - 11x + 30 = 0

Factorise

(x - 5)(x - 6) = 0

x - 5 = 0 Or x - 6 = 0

x = 5 Or x = 6

d) ,   or

Step-by-step explanation:

Let the number be ''.

According to the given statement, the equation is:

Solving the equation:

Factorizing the equation for the value of ''

Taking common from the equation to make the factors of the equation and equating it to zero.

x=5 Or x=6

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

i believe the answer is d.

hope it you! : d
