D and e are equivalent
if you plug in 1,2,3 for X for each equation you can see only d and e are equivalent to the original this is because (50/5)^x and 50^x/5^x simplified is still 10^x
1. 12a²b² + -7a²b² + 9a²b²
= 14a²b² (the terms a²b² are like terms so don't look at them, just add 12 + (-7) + 9.
= 14 (ab)² (you can write like this too because both a & b are squared).
2. y² - (-5y²)
= 6y² (subtract -5 from 1, y² is the like term).
Answer:
She needs to fill ft³ in order to fill the sandbox completely.
Step-by-step explanation:
length = = feet
width = 5 feet
depth = feet
Sandbox is just like a rectangular prism. In order to fill the sandbox completely, we need to determine the volume.
Thus, the formula to find the volume of a rectangular prism can be computed using the formula
ft³
Thus, she needs to fill ft³ in order to fill the sandbox completely.
Answer:
-7.55y +81
Step-by-step explanation:
75-3.55y-4y+6
Combine like terms
-3.55y-4y +6+75
-7.55y +81

<u>Explanation</u>
</span><span>The formula for calculating the area of a circle is;
Area = πr^2
Where π = 3.142
r = radius of the circle.
When a sector of the circle is involve area is a fraction of the whole circle and it is given by;
Area of a sector = θ/360 πr^2
Where ϴ = angle that makes the sector
So, area = 120/360 π9^2=</span>27π
