Yes, that's correct.

Here's another way to approach it:

                                          <u>2 (x + 1) + 3 = 7</u>

Subtract  3  from each side:    2 (x + 1) = 4

Divide each side by  2 :                x + 1 = 2

Subtract  1  from each side:          <em>    x  =  1


</em>

<span>You betcha! Your work is correct! Here is a little different way to solve it. So you can choose which one is simpler for you!

2(x+1)+3=7

Simplify both sides of the equation.

2(x+1)+3=7

Simplify

2x+5=7

Subtract 5 from both sides.

2x+5−5=7−5

2x=2

Divide both sides by 2.

2x / 2=2 / 2

x=1</span>

The measure of the unknown angles in the kite are as follows;

  • x = 66 degrees
  • y = 158 degrees

<h3>How to find the measure of a kite?</h3>

A kite has two pairs of adjacent equal sides.

In other words, a kite is a quadrilateral that has 2 pairs of equal-length sides and these sides are adjacent to each other.

One pair of opposite angles is equal. Diagonals are perpendicular to each other.

A kite has four interior angles and the sum of these interior angles is 360°

Therefore, the measures of the

x = 66 degrees.

Let's find y.

y = 360 - 70 - 66 - 66

y = 158 degrees.

<span> (x + 3) • (x - 12)
</span>

The first term is, <span> <span>x2</span> </span> its coefficient is <span> 1 </span>.
The middle term is, <span> -9x </span> its coefficient is <span> -9 </span>.
The last term, "the constant", is <span> -36 </span>

Step-1 : Multiply the coefficient of the first term by the constant <span> <span> 1</span> • -36 = -36</span> 

Step-2 : Find two factors of  -36  whose sum equals the coefficient of the middle term, which is  <span> -9 </span>.

<span><span>     -36   +   1   =   -35</span><span>     -18   +   2   =   -16</span><span>     -12   +   3   =   -9   That's it</span></span>


Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -12  and  3 
                     <span>x2 - 12x</span> + 3x - 36

Step-4 : Add up the first 2 terms, pulling out like factors :
                    x • (x-12)
              Add up the last 2 terms, pulling out common factors :
                    3 • (x-12)
Step-5 : Add up the four terms of step 4 :
                    (x+3)  •  (x-12)
             Which is the desired factorization

Final result :<span> (x + 3) • (x - 12)</span>
