Step-by-step explanation:
3a^4 -2a^2 + 5 - 10 -(2a^4 +4a^2 + 5a -2)
as given.. i'm wondering if the 5 in the first group is really 5a.. hmmm
I'm guessing that it is... soooo distribute the minus sign
= 3a^4 - 2a^2 +5a -10 -2a^4 -4a^2 -5a +2
= a^4 -6a^2 -8 :) voila that's your answer

Two less than three times a number is the same as six more than twice the number. Write an equation and solve to find the number.
Answer: 8
Step-by-step explanation:
Let the number be represented by x.
Two less than three times a number is the same as six more than twice the number. This will be:
(3 × x) - 2 = (2 × x) + 6
3x - 2 = 2x + 6
Collect like terms.
3x - 2x = 6 + 2
x = 8.
The number is 8
What is the slope of D and E??
Answer:
-4 and 0
Step-by-step explanation:
Rise over Run would give us the slope.
In the first graph, It goes down 4 while it goes 1 to the right.
This means that -4/1 = -4.
The second graph does not go up or down, meaning 0, while it goes 1 to the right.
This means that 0/1 = 0.

Tia cut a 4-meter 8-centimeter wire into 10 equal pieces. Marta cut a 540-centimeter wire into 9 equal pieces. How much longer is one of Marta’s wires than one of Tia’s?
First, Tia’s wire is 4 meters and 8 centimeters long, so that means it’s 408 centimeters long, then you divide that by 10:
tia = 408/10 = 40.8 cm
Now, Marta’s wire is 540 centimeters long and we have to divide that into 9 pieces:
Marta = 540/9 = 60 cm
Finally subtract Marta’s and Tia’s pieces: 60 - 40.8 = 19.2
So Marta’s pieces are 19.2 centimeters longer than Tia’s
Answer:
19.2

HELPPPP
Answer:
3.33%
Step-by-step explanation:
Given that :
Final amount A= 320
Principal P = 300
Time (t) = 2 years
Yes, the information is enough to obtain the interest rate :
Using the relation :
A = P(1 + rt)
r = interest rate
320 = 300(1 + r*2)
320 = 300(1 + 2r)
320/300 = 1 + 2r
1.0666666 = 1 + 2r
1.0666666 - 1 = 2r
0.0666666 = 2r
r = 0.0666666 / 2
r = 0.0333333
(0.0333333) * 100% = 3.33%
Based on the information given the interest rate is 53.33%.
Interest rate:Amount= Principal× Interest rate ×Time/100
Let r represent the interest rate
Hence:
320 = 300×r×2 years/100
320×100/300×2=r
r=320/3×2
r=160/3
r=53.33 or 53 1/3
Inconclusion the interest rate is 53.33%.

What is the volume of a box with width 2 2/3 inches, length 3 1/3 inches, and height 2 1/3 inches ?
Answer:
The volume of a box is:
V = 560 cubic inches or [tex]20\frac{20}{27}[/tex] cubic inches.
Step-by-step explanation:
Given
The width of a box = w = 2 2/3 inches
i.e. [tex]\:w=2\frac{2}{3}=\frac{8}{3}[/tex]
The length of a box = l = 3 1/3 inches
i.e. [tex]l=\:3\frac{1}{3}=\frac{10}{3}[/tex]
The height of a box = h = 2 1/3 inches
i.e. [tex]\:h=2\frac{1}{3}=\frac{7}{3}[/tex]
Using the formula to determine the volume of a box
[tex]V=w\times l\times h[/tex]
substitute [tex]\:w=2\frac{2}{3}=\frac{8}{3}[/tex], [tex]l=\:3\frac{1}{3}=\frac{10}{3}[/tex] and [tex]\:h=2\frac{1}{3}=\frac{7}{3}[/tex],
[tex]V=\frac{8}{3}\times \frac{10}{3}\times \frac{7}{3}[/tex]
Apply the fraction rule: [tex]\frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}[/tex]
[tex]=\frac{8\times \:10\times \:7}{3\times \:3\times \:3}[/tex]
[tex]=\frac{560}{27}[/tex] or [tex]20\frac{20}{27}[/tex] cubic inches
Therefore, the volume of a box is:
V = 560 cubic inches or [tex]20\frac{20}{27}[/tex] cubic inches.

What is the volume of a cylinder?The volume of the cylinder is the product of the height, pie, and square of the radius.
The volume of the cylinder = [tex]\pi r^{2} h[/tex]
A.
a) The height of the cylinder is given as 11 in and the radius is 6 in.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 6^2 x 11
= 1244.07cubics in
b) The height of the cylinder is given as 30 in and the radius is 24 in.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 24^2 x 30
= 54286.72 cubics in
c) The height of the cylinder is given as 21 in.
The radius of the base of the cylinder is given as 19 in.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 19^2 x 21
= 23816.41 cubics in
B.
d) The height of the cylinder is 9ft the radius is 3 ft.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 3^2 x 9
= 254.47 cubics ft
e) The height of the cylinder is 8 ft the radius is 13 ft.

= 3.14 x 13^2 x 8
= 4247.43 cubics ft
f) The height of the cylinder is 27 ft the radius is 16 ft.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 16^2 x 27
= 21714.69 cubics ft
g) The height of the cylinder is 15 ft the radius is 10 ft.
