Answer:
<u>The solutions to this quadratic equation are 10 and 3.</u>
Step-by-step explanation:
1. Let's recall the formula for solving this type of equations, called quadratic equations:
x = ( - b +/- √ b² - 4ac)/ 2a
The equation given is x2 – 13x + 30 = 0,
where a = 1, b = - 13 and c = 30
Now replacing with the real values, we have
x = [ - (-13) +/- √ (-13)² - 4 * 1 * 30] / 2 * 1
x = [ 13 +/- √ 169 - 120] / 2
x = [13 +/- √ 49]/ 2
x = [ 13 +/- 7 ]/ 2
<u>x₁ = 13 + 7/2 = 20/2 = 10</u>
<u>x₂ = 13 - 7/2 = 6/2 = 3</u>
2 because the others aren’t factors of both
Answer: 5
Step-by-step explanation:
The degree is 
. Setting this equal to 10, we get m = 5.
Gloria would have worked six hours which would put her at $72.00 but spends $0.50 to travel to and from work and that would put her at $71.50
1/10 * 4/10 = 4/100 divide both by 4 it'll be 1/25
