Answer: 1) Let's simplify step-by-step.
x22(x+y)−y2
Distribute:
=(x22)(x)+(x22)(y)+−y2
=x23+x22y+−y2
Answer:
=x23+x22y−y2
2)Let's simplify step-by-step.
x4+x2y2+y4
There are no like terms.
Answer:
=x4+x2y2+y4
Answer:
A. 312 cm²
Step-by-step explanation:
The figure compromises of a rectangle and 2 equal triangles.
Area of the figure = area of the rectangle + area of the two triangles
Area = L*W + 2(½*b*h)
Where,
L = 16 cm
W = 12 cm
b = 12 cm
h = 10 cm
Plug in the values
Area = 16*12 + 2(½*12*10)
= 192 + 120
= 312 cm²
Answer:
4
Step-by-step explanation:
40(105/100)=42
.........................
1st : Find the volume of the rectangular block:
12 × 10 × 20 = 2400 cm^3.
2nd : Find the volume of a cylinder

Where r is radius & h is height.
so:

= 76.02654222 cm^3
Lastly, divide the volume of the rectangular block by the volume of the cylinder
2400 ÷ 76.026 = 31.5679226
You can't round it up so the answer is F) 31
