Answer: x³+2x²-15x
Step-by-step explanation:
1. Expand
(x²-3x)(x+5)
2. Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd
x³+5x²−3x²−15x
3. Collect like terms
x³+(5x²−3x²)−15x
4. Simplify
x³+2x²-15x
Hope this helps, have a BLESSED and wonderful day! ;-)
Answer:
-2/3
Step-by-step explanation:
Okay, this is a fairly simple question.
First, you want to pick two pairs of coordinates (X,Y).
In this case, I chose (-3, 5) and (3, 1)
Now, you want to use the formula to find slope : y2-y1/x2-x1
1-5/3-(-3)
-4 divided by 6
=-2/3
Answer:
A. absolute value f(-5)=6
B. linear g(0.2)= 0.3
C. absolute value p(-3)=13
Step-by-step explanation:
f(-5)=|(-5)-3|-2
=|-8|-2
=8-2
=6
g(0.2)= 1.5(0.2)
=0.3
p(-3)=|7-2(-3)|
=|7+6|
=13
That's the furthest it can be simplified.
Answer:
length of rectangle = 32.25 cm
Width of rectangle = 10.75 cm
Step-by-step explanation:
Let the length of rectangle be x.
And width of rectangle be y.
According to the problem,
x = 3y {Since the length of a rectangle is equal to triple the width}
Also,
Perimeter of rectangle = 86
or 2 (x + y) = 86
Plug x =3y in the above equation
We get, 2(3y + y) = 86
2 * 4y = 86
4y = 43
y = 43/4 = 10.75
So, length of rectangle = 3 * 10.75 = 32.25cm
Width of rectangle = 10.75cm
