Answer:
24x+8+−10x+5
Step-by-step explanation:
Do distributive property.
4*6x=24x
4*2=8
5*2x=10x
5*-1=-5
So 24x+8+−10x+5 is your answer.
Answer:
A= 7
B= 154
Step-by-step explanation:
A: the radius is half of the diameter
B: pie*radius to the second power
4/5 of the original amount at the start of the month will remain. The amount at the start of every month will change. Thus:
an = 4/5 (an-1) ; where a1 = 500.
If x=width, then the equation would be:
x(x+10)=20,000
The length is 10 meters longer than the width(x), so the length is x+10.
To get the area(20,000) you multiply width by length, hence x(x+10).
Hope this helps.
