Answer:
I guess...
Step-by-step explanation:
Since QR and PN are parallels, I think what happens in MN and MP is proportional, so:
RN = x
8 is to 10 as
5 is to x
8 * x = 5 * 10
8x = 50
x = 50 / 8
x = 6.25
RN = 6.25
Solution:
<u>Note that:</u>
- Given expression: (x² + 4x) − (x² + 6x − 3)
<u>Remove the brackets</u>
- (x² + 4x) − (x² + 6x − 3)
- => x² + 4x - x² - 6x + 3
<u>Combine like terms</u>
- x²(1 - 1) + x(4 - 6) + 3
- => x²(0) + x(-2) + 3
- => -2x + 3
A. rise over run. 8/24=1/3
slope:1/3
b. find the cost per pound 11.60/4=2.90
then multiply by the amount of pounds 2.90*3.5=10.15
$10.15
