Answer:
Step-by-step explanation:
The first thing that I noticed was that all of the terms had a common factor of 
. You can therefore factor that out first:
Now, you have a quadratic equation inside the parentheses. Factoring, you find that the roots are -0.2 and 3, meaning that you can further factor this expression to be:
Hope this helps!
Answer:
6 hours
Step-by-step explanation:
Let
x----> the number of hours worked at the donut shop
y----> the number of hours worked at the school bookstore
we know that
x+y=20
x=20-y -----> equation A
10.25x+8.75y=196 -----> equation B
Substitute equation A in equation B and solve for y
10.25(20-y)+8.75y=196
205-10.25y+8.75y=196
10.25y-8.75y=205-196
1.5y=9
y=6 hours at the school bookstore
Answer: 25 in
Step-by-step explanation:
<u>Due to the use of the term "hypotenuse" I will assume the triangle is a right triangle.</u>
<u></u>
According to pythagorean theorem, 7²+24²=(hypotenuse)²
49+24²= (hypotenuse)²
49+576= (hypotenuse)²
625 = (hypotenuse)²
25 = hypotenuse
Hope it helps <3 :D
In order to find which is the answer, we will go step-by-step. Numbers that are not followed by I are drawn on the Real Axis and the other ones are drawn on the Imaginary Axis. You go first on the Real Axis and then on the Imaginary Axis and intersect those 2 points. If a number does not have an imaginary or real part you can assume that is equal to 0. As you can notice the number that is not in the shaded area is <span>2 − I</span>
