First use the distributive property by multiplying the 3 with each term inside the parentheses:
-8 + 3c + 3 + c
Now combine like terms:
-8 + 3 = -5
3c + c = 4c
Combine for final answer:
-5 + 4c which can also be written as 4c-5
Answer:
first let's multiply 3 by the bracket
-8+3*c+3*1+c=-8+3c+3+c
then add the numbers that have the same variables -8+3+3c+c
=-8+3+4c then add the numbers
=-5+4c is the answer
you can also write it like this
4c-5

Vince is saving for a new mobile phone. The least expensive model Vince likes costs $225.90. Vince has saved $122.35. He used this solution to determine how much more he needs to save.
225.90 less-than-or-equal-to 122.35 + a. 225.90 minus 122.35 less-than-or-equal-to 122.35 minus 122.35 + a. 103.55 less-than-or-equal-to a.
Vince says that based on the solution, he should save a maximum of $103.55.
Is Vince correct?
Vince is correct because he found the correct solution to the inequality.
Vince is correct because he should save at least $103.55.
Vince is not correct because he wrote the wrong inequality to represent the situation.
Vince is not correct because he should have interpreted the solution as having to save a minimum of $103.55.
Answer:
Vince is not correct because he should have interpreted the solution as having to save a minimum of $103.55.

Find the area of the figure.
Step-by-step explanation:
Area of Rectangle at the top =
Length x Width
[tex] = 3.5 \times 3 \\ = 10.5 {mm}^{2} [/tex]
Area of Quarter- Circle = 1/4 x Area of Circle
[tex] = \frac{1}{4} \pi {r}^{2} \\ = \frac{1}{4} \pi( {3.5}^{2} ) \\ = 3 \frac{1}{16} \pi {mm}^{2} [/tex]
Area of Rectangle at the right = Length x Width
[tex] = 5.5 \times 3.5 \\ = 19.25 {mm}^{2} [/tex]
Total Area = Area of 2 Rectangles + Area of Quarter Circle
[tex] = 10.5 + 3 \frac{1}{16} \pi + 19.25 \\ = 29.75 + 3 \frac{1}{16}\pi \\ = 32 \frac{13}{16}\pi {mm}^{2} [/tex]

Factor by grouping:
3x^(3)-6x^(2)+15x-30
the answer would be b on scholar
Answer:
3 (x² + 5) (x - 2)
Step-by-step explanation:
3x³- 6x² + 15x - 30
=> 3 (x³ - 2x² + 5x - 10)
=> 3 [x²(x - 2) + 5 (x - 2)]
=> 3 (x² + 5) (x - 2)

PLEASE HELP! What is the ratio of the volumes of two spheres, if the ratio of their radii is 13: 9
Answer:
[tex] V_1 : V_2= 2197 : 729[/tex]
Step-by-step explanation:
Let the volumes of both the spheres be [tex] V_1, \:V_2[/tex] and their radii be [tex] r_1, \:r_2[/tex] respectively.
[tex] \huge r_1 : r_2= 13 : 9[/tex] (given)
[tex] \implies\huge \frac{r_1}{r_2}= \frac{13}{9}.....(1)[/tex]
[tex] \huge \frac{V_1}{V_2}=\frac{\cancel {\frac{4}{3} \pi} r_1^3}{\cancel {\frac{4}{3} \pi} r_2^3}[/tex]
[tex] \huge \frac{V_1}{V_2}=\frac{ r_1^3}{r_2^3}[/tex]
[tex]\huge \frac{V_1}{V_2}=\bigg(\frac{ r_1}{r_2}\bigg) ^3..... (2)[/tex]
From equations (1) & (2), we have:
[tex]\huge \frac{V_1}{V_2}=\bigg(\frac{13}{9}\bigg) ^3[/tex]
[tex] \huge \frac{V_1}{V_2}=\frac{2197}{729}[/tex]
[tex] \huge \therefore V_1 : V_2= 2197 : 729[/tex]
Thus, the ratio of the volumes of two spheres would be 2197 : 729.
Answer:
2197:729

Decide whether the given expression is a polynomial and tell why or why not.
5. 3x2 – 5x + 2
Answer:
3x² – 5x + 2 is a polynomial because:
Exponents are whole numbers, and the expression has at least 1 term.
Exponents other than whole numbers can take the form of variables in denominators, and roots which we don't want.

Answer:
B. A = 1/2(7)h
Step-by-step explanation:
Formula for area of triangle = 1/2 x base x height
H is the height of the triangle.
7cm is identified as the base of the triangle.
1/2(7)h is also the same thing as 1/2 x 7 x h basically.
Answer:
B
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 7 and h = h , then
A = [tex]\frac{1}{2}[/tex] (7) h → B

Answer:
I belive the answer is A
Step-by-step explanation:
So any answer with 22t would make sense, so you have A and C. In C though, it is subtracting 22, but since 6195 is the total it would have to include the 22 so it is A.

Answer:
D
Step-by-step explanation:

Explain why this is wrong:
(Student's Solution): "Factor the polynomial"
y^2-6y+9=y^2-2(y)(3)+3^2 = (y-3)(y+3)
Note: Please help, I have been working on this for like 4 days im so tired.
Answer:
See below.
Step-by-step explanation:
y^2 - 6y + 9 can be changed correctly into y^2 - 2(y)(3) + 3^2.
Up to here, it's correct.
The right side above shows a polynomial that is the square of a binomial.
It factors into (y - 3)^2.
The correct factorization is (y - 3)^2.
The incorrect factorization of the student's solution is the product of a sum and difference.
The product of a sum and a difference is the correct factorization for a difference of squares.
For example, y^2 - 9 is the same as y^2 - 3^2 and is a difference of squares.
It factors into (y + 3)(y - 3), a product of a sum and a difference.

The animal department wants to estimate the kangaroo population. So they marked 30 kangaroos with paint. These kangaroos were then released into the jungle. After four months 600 kangaroos were caught. Among these Kangaroo, 18 were marked. To the nearest whole number,what is the best estimate for the kangaroo population?
Answer:
1000
Step-by-step explanation:
From the above question
We have the following parameters
30 were intially Marked
600 were caught and out of it 18 was marked
The formula for the best estimate of the population is calculated as:
Total population = Initial marked kangaroo × Number of caught kangaroo/Number of kangaroo marked after they were caught
= 30 × 600/18
= 1000
