(a^3 - 2a + 5) - (4a^3 - 5a^2 + a - 2)
=a^3 - 2a + 5 - 4a^3 + 5a^2 - a + 2
= -3a^3 + 5a^2 - 3a + 7
Subtract 49 by its negative so now
x^2-16x=-49
then move -16 so
x^2=-49+16x
then add -49 and 16 so then you get
X^2+your answer)
then find the square root because this was in exponential form so find the square root of x^2 and of your answer so
X= Your answer
do the work
A.
P=2(L+W)
W=29
P is at least (means greater than or equal than ) 134
so
134≤2(L+29) is the inequality
B.
solve
divide both sides by 2
67≤L+29
minus 29 from both sides
38≤L
Length is any value greater than or euqal to 38ft
Answer:
<u><em>-7624928000 </em></u><em>is the right answer.</em>
Step-by-step explanation:
<em> (-7624928) × 997 + 7624928 × (-3)</em>
<em>= -7602053216 + (-22874784)</em>
= <u><em>-7624928000</em></u><em> </em><u><em>Ans..</em></u>

Breanna used 
pounds of clay for her project.
Step-by-step explanation:
Step 1; First, we must convert the mixed fractions into improper fractions. To do that we multiply the whole number with the denominator and add with it the numerator while the denominator remains the same. To convert this fraction 1 
, we multiply 1 with 8 and then add 4 and keep the 8 as the denominator so we get
1 = (1 × 8) + 5 / 8 = 
.
Step 2; After conversion, it's just a matter of subtraction. To calculate the clay she used for her project, we subtract the clay she had after from the clay she had before doing the project. While subtracting two fractions, if denominators are equal we subtract the numerators and keep the denominator the same.
- 
= 
= .
So Breanna used pounds of clay for her project.
