Solve the equation. x^2 − 6x − 7 = 0

NeX [460]

Here is your answer

D) x= -1 or x= 7

REASON:

Given equation-

${x}^{2}-6x-7=0$

Split the middle term

${x}^{2}+x-7x-7=0$

Taking common from the terms

$x(x+1)-7(x+1)= 0$

$(x+1)(x-7)= 0$

Now,

x+1=0 or x-7=0

x= -1 or x= 7

How many tenths are there in 4/5

il63 [147K]

What we have to solve is:

$\frac{4}{5} = \frac{x}{10}$

we should multiply both sides by10, to get the "x" by itself:

$\frac{4*10}{5} = \frac{x}$

$\frac{4*2}{1} = \frac{x}$

$8 = \frac{x}$
so there are 8 tenths in this number!
