Answer:
Step-by-step explanation:
<u>Step 1:</u>
<em>Equation should be:</em>
<u>Step 2:</u>
<em>Equation should be:</em>
<u>Step 3:</u>
- Factoring

- The first term is
. It's coefficient is 3. - The middle term is +18x, it's coefficient is 18.
- The last term, "the constant", is -13.
<em>Step 1</em>:
- Multiply the coefficient of the first term by the constant 3 * -13 = -39
<em>Step 2:</em>
- Find two factors of -39 whose sum equals the coefficient of the middle term, which is 18 .
- -39 + 1 = -38
- -13 + 3 = -10
- -3 + 13 = 10
- -1 + 39 = 38
- Observation : No two such factors can be found !!
- Conclusion : Trinomial can not be factored
<u>Solution:</u>
- <u />
.
You know that
5² = 25
6² = 36
so √28.8 must lie between √25 = 5 and √36 = 6.

Hi... Your answer is... A=1
Answer:
49 +80= 129
180 - 129= 51
Opposite are equal.
Extend line of QR - so, the x shape made can be used to calculate what x is.
51 + 51 = 102
Reflex angles adds to 360
360-102= 258 of the other opposite angles left.
258/2 = 129 since opposite angles are equal.
Answer is 129 degrees
