D is the correct answer, first you have to write to you equations 1+ the absolute value of 2+ X equals nine and 1+ the absolute value of 2+ X equals -9 then you must subtract one from both sides

Write an expression <br>the quantity of 7+x, squared

Ray Of Light [21]

Answer:

$\huge \boxed{(x+7)^2 }$

Step-by-step explanation:

The quantity x + 7 is squared.

$(x+7)^2$

Expand the brackets and simplify the expression.

$(x+7)(x+7)$

$x(x+7)+7(x+7)$

$x^2 +7x+7x+49$

$x^2 +14x+49$

We can leave the expression in factored form.

What is two numbers that multiply to 24 but add to 25?

lesya [120]

X, y - the numbers

$xy=24 \\
x+y=25 \\ \\
\hbox{solve the second equation for y:} \\
x+y=25 \\
y=25-x \\ \\
\hbox{substitute 25-x for y in the first equation:} \\
x(25-x)=24 \\
25x-x^2=24 \\
-x^2+25x-24=0 \\
-x^2+24x+x-24=0 \\
-x(x-24)+1(x-24)=0 \\
(-x+1)(x-24)=0 \\
-x+1=0 \ \lor \ x-24=0 \\
x=1 \ \lor \ x=24 \\ \\
y=25-x \\
y=25-1 \ \lor \ y=25-24 \\
y=24 \ \lor \ y=1$

The numbers are 1 and 24.
