The answers are that the number can equal -4 or 1.

You can find this by setting the number equal to x.

x^2 (The square of a number) + 3x (three times a number) = 4

x^2 + 3x = 4 ---> subtract 4 from each side
x^2 + 3x - 4 = 0

Then you can factor this to find the answers

(x - 4)(x + 1) = 0

Set both equal to 0 and solve.

Answer:

Step-by-step explanation:

$3x+7\\\\3\left(x+\dfrac{7}{3}\right)=(3)(x)+(\not3)\left(\dfrac{7}{\not3}\right)=3x+7\qquad\boxed{YES}\\_{\text{used the distributive property: a(b + c) = ab + ac}}\\\\x+x+x+5+1=(x+x+x)+(5+1)=3x+6\neq3x+7\qquad\boxed{NO}\\\\8x+3-5x+4=(8x-5x)+(3+4)=3x+7\qquad\boxed{YES}\\\\7x+3\neq3x+7\qquad\boxed{NO}$
