Our first expression is 
. Upon distributing the exponent 4 on all the terms, we get:
Therefore, your answer is correct for this part. :)
Second expression is 
. Upon distributing the exponent -2 on all the terms, we get:
Your second answer is correct too.
Our third expression is 
. Upon distributing the exponent 2 on all the terms, we get:
This one is not correct. Your answer would have been correct, if the exponent were -2 instead of 2 in this part.
Our forth and last expression is 
. Upon distributing the exponent -5 on all the terms inside the parenthesis, we get:
Therefore, your answer for this part is also correct.
Looking at your work, I don't think you made a mistake in number 3 also, probably mis-typed the question while writing here :)
Answer:
X=5
Step-by-step explanation:
Look at the problem | y=15-3x
5×3 is 15.
y=0
15-15=0
Therefore that's the answer.
you're welcome, get better!! :D
Answer:
Yes your friend is correct. If you buy five bags of the 2 lb bag then you will pay $0.54 less than what you would have to pay for a 10lb bag.
Step-by-step explanation:
1.29 x 5 = 6.45
6.99 - 6.45 = 0.54
Answer:
Q. 11 x=29
Q. 12 x=24
Step-by-step explanation:
Q.11
sum of all sides of triangle = 180°
(2x+20)+(x+10)+(2x+5)=180°
5x+35=180°
5x=180°-35
5x=145°
x=145/5
x=29°
Q.12
sum of all sides of triangle=180°
96+(2x)+(x+12)=180°
3x+108=180°
3x=180-108
3x=72
x=72/3
x=24
If you are trying to find the area of the triangle, you would do base x height.
14 x 5
So the answer would be 70
