Answer:
-15 and -2
Step-by-step explanation:
Since a negative times a negative equals a positive, but when added, still stays a negative, the factors must both be negative.
Negative Factors of 30:
-30 + -1 = -31
-15 + -2 = -17
-10 + -3 = -13
-6 + -5 = -11
The two factors of 30 that add up to -17 are -15 and -2.
Hope this helps. Have a nice day.
Answer:
The zeros of f(x) are: (x - 1), (x - 3) and (x - 8)
<em></em>
Step-by-step explanation:
Given


Required
Find all zeros of the f(x)
If
then:

And
is a factor
Divide f(x) by x - 8

Expand the numerator

Rewrite as:

Factorize

Expand

Factorize


Multiply both sides by x - 8

<em>Hence, the zeros of f(x) are: (x - 1), (x - 3) and (x - 8)</em>
Set up your two equations:
<span>9x+7y=53 </span>
<span>3x+5y=25 </span>
<span>X=cost per pound of jelly bean </span>
<span>Y=cost per pound of trail mix </span>
<span>Multiply the second equation by (-3): </span>
<span>-9x-15y=-75 </span>
<span>+ 9x+7y=53 <---- copy first equation and add them </span>
<span>—————— </span>
<span>0x-8y=-22 </span>
<span>Then solve for y: </span>
<span>Y=2.76 this is your cost per pound of trail mix. </span>
<span>Then plug y back in to one of the original equations and solve for x: </span>
<span>3x+7(2.75)=25 </span>
<span>X=3.75 this is you cost per pound of jelly beans</span>
I won't tell you the answer but I'll tell you how to do it
first, find the area of the rectangle (lxw)
Next, find area of the triangle (BxHx.5)
Then, subtract the area of the rectangle to the area of the triangle
