Answer:
Step-by-step explanation:
Volume is the combination of 2 volumes
- 1. Dimensions: 0.5 m, 05 m and 1.5 - 1 = 0.5 m
- 2. Dimensions: 1 m, 0.5 m and 0.75 m
So the volume is:
- 0.5*0.5*0.5 + 1*0.5*0.75 = 0.5 m³
Answer:
Difference of squares:
y^4−25
16x^2−81
Not difference of squares:
20m^2n^2−121
p^8−q^5
Step-by-step explanation:
y^4−25
(y²)² - 5²
16x^2−81
(4x)² - 9²
20m^2n^2−121
20 is not a perfect square
p^8−q^5
q⁵ is not a perfect square
Answer:
3
Step-by-step explanation:
32 - 20 = 12
12/4 = 3
This assumes that by remainder they mean they twelve feet left over and not the twenty feet removed. This is likely what it means.
<span>r/7 = -8
-----------------
Simplify
1/7r=-8
-------------------------
Multiply each side by 7
7 * 1/7r = 7 * -8
r = -56
--------------------------------------------
A.) R = -56 is your answer</span>
