Solve the proportion for x.

Delvig [45]

$\frac{x}{8} = \frac{8}{64} \\ 64x = 8 \times 8 \\ 64x = 64 \\ x = \frac{64}{64} \\ \boxed{x = 1}$

Proportion for x is 1.
Use cross multiplication.

Tanzania [10]

Answer:

step 2

Step-by-step explanation:

we have

$x^{2} +10x-49=0$ ---> given problem

step 1

Move the constant to the right side

$x^{2} +10x=49$

the step 1 is correct

step 2

Complete the square

$x^{2} +10x+5^2=49+5^2$

$x^{2} +10x+5^2=74$

The step 2 is not correct

step 3

Rewrite as perfect squares

$(x+5)^{2}=74$

step 4

take square root both sides

$x+5=\pm\sqrt{74}$

step 5

Find the values of x

$x=-5\pm\sqrt{74}$

$x=-5+\sqrt{74}$

$x=-5-\sqrt{74}$
