Answer:
YeS, it is a solution
Step-by-step explanation:
Here, we want to check if -6 is a solution to the question
What we have to do is to replace x by -6
If what we have on the left equals that on the right, then -6 is a solution
Thus, we have it that;
3(2(-6) -8)
= 3(-12-8)
= 3(-20) = -60
for the right hand side
-4 (15) = -60
This means both sides are equal and that -6 is a solution
-4x^2-5(x+3)+x^2
First, combine like terms.
-4x^2+x^2= -3x^2
-3x^2-5(x+3)
Distribute the 5.
-3x^2-5x-15 <=== the simplified answer
I hope this helps!

Answer:
Step-by-step explanation:
There are two other important distances on a circle, the radius (r) and the diameter (d). The radius, the diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pi you can calculate the circumference. The diameter is the distance from one side of the circle to the other at its widest points. The diameter will always pass through the center of the circle. The radius is half of this distance. You can also think of the radius as the distance between the center of the circle and its edge.
This diagram shows the circumference, diameter, center, and radius on a circle.
Answer:
Austin paid 9 bucks more
Step-by-step explanation:
Zach : original cost is 60 bucks.....on sale for 35% off....means he paid (100% - 35%) = 65%.
65% of 60 = 0.65(60) = 39 <=== what Zach paid
Austin : original price 60 bucks...on sale for 20% off...so he paid 80%
80% of 60 = 0.8(60) = $ 48 <=== what Austin paid
Austin paid (48 - 39) = $ 9 more then Zach
