Complete the square for each expression. Then factor the Trinomial <br> x^2+8x

Goryan [66]

The value of x is $x=0$ or $x=-8$

Step-by-step explanation:

The expression is $x^{2} +8x=0$

To complete the square, the equation is of the form $ax^{2} +bx+c=0$

The constant term c can be determined using, $c=\left(\frac{\frac{b}{a}}{2}\right)^{2}$

$\begin{aligned}c &=\left(\frac{8}{2}\right)^{2} \\&=\left(\frac{8}{2}\right)^{2} \\c &=4^{2} \\c &=16\end{aligned}$

Rewriting the expression $x^{2} +8x=0$ and factoring the trinomial, we have,

$\begin{array}{r}{x^{2}+8 x+16=16} \\{(x+4)^{2}=16}\end{array}$

Taking square root on both sides, we get,

$\begin{aligned}&x+4=\sqrt{16}\\&x+4=\pm 4\end{aligned}$

Either,

$\begin{array}{r}{x+4=4} \\{x=0}\end{array}$ or $\begin{array}{r}{x+4=-4} \\{x=-8}\end{array}$

Thus, the value of x is $x=0$ or $x=-8$

Joe and Josh each want to buy a video game. Joe has $14 and saves $10 a

Aleks [24]

Answer:

Number of week they have same amount = 4 week

Step-by-step explanation:

Given:

Amount Joe have = $14

Joe's saving per week = $10

Amount Josh have = $26

Josh saving per week = $7

Find:

Number of week they have same amount

Assume;

Number of week they have same amount = a

So,

(14 + 10a) = (26 + 7a)

3a = 12

a = 4

So,

Number of week they have same amount = 4 week

the first term in a geometric series is 64 and the common ratio is 0.75. Find the sum of the first 4 terms in a series.

Rufina [12.5K]

u0 = 64 with u(n+1) = un *0.75

u3 = 64 *0.75^3 = 27

sum is : 64 * ( 0.75^4 -1) / 0.75-1 = 175

manual proof : 64 + 48+36+27 = 175
