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

Answer:
80 degrees
Step-by-step explanation:
ALL TRIANGLES MUST EQUAL 180 DEGREES!
180-70-30 = 80
Say it with me.
<em>ALL TRIANGLES MUST EQUAL 180 DEGREES!</em>
<em>ALL TRIANGLES MUST EQUAL 180 DEGREES!</em>
<em>ALL TRIANGLES MUST EQUAL 180 DEGREES!</em>
Also, triangle CED reflects over the invisible y-axis. Angle C is shared = 70. Angle E is Angle A, and Angle B is Angle D (which is 80 degrees).
Answer:
he paied 14 dollars and 31 cents
Step-by-step explanation:
If i read it right you just add 8.49 and 5.82
(2300 / 4500) * 100 = 51.1%
Hope this helps! :)
Answer:
an = 1/4 * an-1
a1 = 2
Step-by-step explanation:
2, 1/2, 1/8, 1/32
To find the common ratio, take the second term and divide by the first term
1/2 ÷ 2
1/2 * 1/2
1/4
The common ratio is 1/4
1/2 * 1/4 = 1/8 and 1/8 *1/4 = 1/32
The first term is a1 so a1 = 2
an = the common ratio * an-1
an = 1/4 * an-1
