Answer:
The value of N = 118
Step-by-step explanation:
750 = 6n + 42
move all the numbers that don't contain n to the right side
6n = 750 - 42
6n = 708
708 / 6 = 118
n = 118
plug the numbers back in
6 ( 118) = 708
708 = 708
plug the 42 back in
708 + 42 = 750
Answer:
2x^{2}-3x-5 = 0
use the formula (b/2)^2 in order to create a new term. Solve for x by using this term to complete the square.
x= 5/2, -1
Hi!
<h3>Let's use the guess and check method. </h3><h3>First, find numbers that when divided, equal 4, and are less than 20. </h3>
- 4/1 = 4
- 8/2 = 4
- 12/3 = 4
- 16/4 = 4
<h3>Now see if any of those pairs of numbers add up to 20. </h3>
- 4 + 1 = 5
- 8 + 2 = 10
- 12 + 3 = 15
- <u>16 + 4 = 20</u>
<h2>The answer is 16 and 4.</h2>
Hope this helps! :)

area of circle = π r²
π r²= 49 π
r²= 49 r= √49 r= 7
circumference of circle = 2 π r
= 2×7 × π
= 14 π
