Talia grouped the terms and factored out the GCF of the groups of the polynomial 15x2 – 3x – 20x + 4. Her work is shown below.
(15x2 – 3x) + (–20x + 4)
3x(5x – 1) + 4(–5x + 1)
Talia noticed that she does not have a common factor. What should she do?
Talia needs to leave the polynomial as is because it is prime and cannot be factored.
Talia needs to group the terms differently.
Talia needs to factor out a negative from one of the groups so the binomials will be the same.
Talia needs to apply the distributive property to get the expression (3x + 4)(5x – 1).
Answer:
Talia needs to factor -1 out of one of the two binomials
Step-by-step explanation:
She could take:
3x(5x - 1) + 4(-5x + 1)
and rewrite it as:
3x(5x - 1) - 4(5x - 1)
= (3x - 4)(5x - 1)

evaluate function expression 5xf(1) + 5xg(9)
Answer:
5x(f+9g)
Step-by-step explanation:
5xf(1)+5xg(9)
Factor out 5.
5(xf+9xg)
Consider xf+9xg. Factor out x.
x(f+9g)
Rewrite the complete factored expression.
5x(f+9g)

The cube root of a number is 2. Write an equation, using x, that represents this situation.
Answer:
x - 8 = 0
Step-by-step explanation:
Since, the cube root of a number is 2.
Let the number be x.
Therefore,
[tex] \sqrt[3]{x} = 2 \\ cubing \: both \: sides \\ {( \sqrt[3]{x})}^{3} = {(2)}^{3} \\ x = 8 \\ x - 8 = 0[/tex]
You and a friend go to Tacos Galore for lunch. You order three soft tacos and five burritos and your total bill is $17.75. Your friend orders four soft tacos and two burritos and paid $12.00.
Answer:
Step-by-step explanation:
let tacos be x and burritos be y
so, your 1st eqn. is 3x + 5y = 17.75
2nd eqn. is 4x+ 2y = 12
Solving the 2 eqns: Multiply eqn 1 with 2 and eqn 2 with 5
So: 6x+10y=35.5
-20x-10y=-60
=-14x=-24.5
x=24.5/14 = 1.75
Substituting the value of x in eqn 1 : (3*1.75)+5y=17.75
y = 2.5
2 cot^2t sin t - cot^2t = 0
2 cot²(t ) sin(t ) - cot²(t ) = 0
cot²(t ) (2 sin(t ) - 1) = 0
cot²(t ) = 0 or 2 sin(t ) - 1 = 0
cot(t ) = 0 or sin(t ) = 1/2
cos(t ) / sin(t ) = 0 or sin(t ) = 1/2
cos(t ) = 0 or sin(t ) = 1/2
[t = cos⁻¹(0) + 2nπ or t = cos⁻¹(0) - π + 2nπ]
or [t = sin⁻¹(1/2) + 2nπ or t = π - sin⁻¹(1/2) + 2nπ]
(where n is any integer)
t = π/2 + 2nπ or t = -π/2 + 2nπ or t = π/6 + 2nπ or t = 5π/6 + 2nπ
Note that the first two families of solutions overlap and can be condensed, so that
t = π/2 + nπ or t = π/6 + 2nπ or t = 5π/6 + 2nπ
y=-0.011x+40.604y = − 0.011 x + 40.604

2) What is the meaning of the slope in that situation?
Answer:
0.11×11%×40.60%×4=0.11×+40%.604
Kash bought 6 notebooks for $15.00. How many notebooks can his sister buy with $10.00?
Answer:
4
Step-by-step explanation:
Making this problem into a proportion we get:
6/$15 = x/$10
Cross multiply 10 and 6, we get 60. Now divide that by 15, you get 4.

Answer:
I think 235.5 mm cubed
Step-by-step explanation:
The formula for the volume of a cone is V=1/3hπr².
1/3 x 9 x π x 5² =
1/3 x 9π x 25 =
1/3 x 225π =
75π
let's say π=3.14
75 x 3.14 = 235.5
A right cone has a slant height of 6 and a radius of 4. What is its surface
area?
A. 40 units^2
B. 56 units^2
C. 24 units^2
D. 16 units^2
The surface area of the cone is 16π square units.
What is the surface area of the cone?The surface area of the cone is given by;
⇒ Area = πrl + πr²
Here, We have;
A right cone has a slant height of 6 and a radius of 2.
Substitute all the values in the formula
⇒ Area = πrl + πr²
⇒ Area = π x 2 x 6 + π x 2²
⇒ Area = 16π
Hence, The surface area of the cone is 16π square units.

Find the volume of the solid obtained by rotating the region bounded by the given curves about the x-axis.
y = 3 − 3x^2, y = 0
Answer: [tex]9.6\pi[/tex]
Step-by-step explanation:
Given
Curve is [tex]y=3-3x^2[/tex]
boundary is y=0 i.e.
[tex]\Rightarrow 0=3-3x^2\\\Rightarrow x^2=1\\\Rightarrow x=\pm 1[/tex]
The volume of solid generated when rotated about the x-axis is
[tex]\Rightarrow V=\int_a^b\pi y^2dx[/tex]
Putting values we get
[tex]\Rightarrow V=\int_{-1}^{1}\pi (3-3x^2)^2dx\\\\\Rightarrow V=\int_{-1}^{1}\pi(9+9x^4-18x^2)dx\\\\\Rightarrow V=\pi \left [ \frac{9x^5}{5} - 6 x^3 + 9 x\right ]_{-1}^{1}\\\\\Rightarrow V=9.6\pi[/tex]

(2x -5) - 1.75(x+4) simplify
Step-by-step explanation:
=0.25x-12 I hope this helped:)
Answer:
0.25x−12
Step-by-step explanation:
(2x−5)−1.75(x+4)
Use the distributive property to multiply −1.75 by x+4.
2x−5−1.75x−7
Combine 2x and −1.75x to get 0.25x.
0.25x−5−7
Subtract 7 from −5 to get −12.
0.25x−12

4/3 (3x-12)=2x+8 what is x
The answer is, X = 12.
hope it helps.
Answer:
x = 12
Step-by-step explanation:
simlify 4/3 * (3x-12)
4x - 16 = 2x + 8
combine like terms, so subtract 2x by 4x
2x - 16= 8
then finish combining like terms, so 16 plus 8
2x = 24
divide 24 by 2
x = 12

the reason physical state affect the rate of a chemical rection
Answer:
Usually reactions speed up with increasing temperature. Physical state of reactants. Powders react faster than blocks - greater surface area and since the reaction occurs at the surface we get a faster rate. The presence (and concentration/physical form) of a catalyst (or inhibitor).
