Well to get to 32 hours and knowing for all 4 days, she worked the same number of hours.
All we have to do is multiply all these numbers by 4 to see which one is equal to 32.
6 * 4 = 28
10 * 4 = 40
8 * 4 = 32
4 * 4 = 16
c. is the correct answer
If the center is at (0, 0) and the vertex is at (20, 0), then the distance, a, is the length from the center to the vertex, 20. The distance from the center to the focus is c. The distance from the center to the focus is 16, so c = 16. The formula we use to find the focus is
. We have our c value and our a value, so we will sub in those to find b.
and 256 = 400 - b^2. -b^2 = -144, so b = 12. There you go!
Answer/Step-by-step explanation:
7x- 4 = -182
<em>Step:</em>
Add 4 to both sides
7x - 4 + 4 = -182 + 4
Simplify
7x = -178
Divide both sides by 7
7x/7 = -178/7
Simplify
x = -178/7
Decimal form = -25.4285714286

Answer:
3x^2−8x−3
Step-by-step explanation:
(3x+1)(x−3)
=(3x+1)(x+−3)
=(3x)(x)+(3x)(−3)+(1)(x)+(1)(−3)
=3x^2−9x+x−3
=3x^2−8x−3
