2. You are able to distribute -5, and you get -5x when it goes into x, and you get positive 10 because it is a negative times a negative. So the answer would be B, -5x + 10
3. On this type of problem, when there is a negative in the middle, you MUST turn it positive. This means you distribute the negative, and everything on the right of the minus sign changes to negative or positive. So it would change to -
(8x-6)+(x-4)
When you add, you get 9x-10, which is C.
4. Simply just add these two, which is what we got to on the last problem, and you get 20x-6, which is choice A.
5. For this, you substitute the numbers in the equation. So it would be -
2(5)-4(-1)
This would equal 14, which is A.
6. You substitute 4 for x, so it would be -
4^2 + 5
4 • 4 + 5
16 + 5
21, Choice B
7. When you combine like terms here, the 3y’s cancel out because they equal each other, so the answer would just be 19, which is A.
The answers for the given Expression are;
1) 15(x+2)
2) -5x + 10
3) 9x - 10
4) 20x - 6
5) 14
6) 21
7) 19
What is an Expression?Numbers, symbols and operators (such as and times) grouped together that show the value of something.
Given are the Expressions to solve;
1) 15x + 30
GCF for this Expression is 15 therefore
15x + 30 = 15(x+2)
2) -5(x - 2) = -5 + 10
3) (8x - 6) - (-x + 4) = 8x - 6 + x - 4 = 9x - 10
4) (11x - 2) + (9x - 4) = 20x - 6
5) 2x - 4y when x = 5 and y = -1
2x - 4y = 2*5 - 4*(-1) = 14
6) x² + 5 when x = 4
4² +5 = 16 + 5 = 21
7) -3y + 12 + 3y + 7 = 19
Hence, The Answers are :
1) 15(x+2)
2) -5x + 10
3) 9x - 10
4) 20x - 6
5) 14
6) 21
7) 19

Given : A toy car is placed on the floor. Its movement details are given
Answers
Answer:
Given : A toy car is placed on the floor. Its movement details are given
To find : Distance covered by Car & graph to be plotted
Solution:
Start from rest
u = 0 at t = 0
Constant acceleration for 3 sec reaching velocity 4 m/s
V = U +at
=> 4 = 0 + a(3)
=>a = 4/3 m/s²
Distance here S = ut + (1/2)at²
S = 0 + (1/2)(4/3)3²
=> S = 6 m
deceleration of 0.5 m/s² for 4 sec
=> v = 4 - (0.5)4
=> v = 2 m/s
Distance here = 4(4) - (1/2) (0.5)4²
= 16 - 4
= 12 m
Total Distance = 6 + 12 = 18 m
Total Distance traveled by toy Car = 18 m

Step-by-step explanation:

Answer:
12 years
Step-by-step explanation:
144,000.00 / 2,000.00 is 72 times that he deposited 2,000.00 in order to get 144,000.00. If he deposits once every 2 months then he would have deposited 72 months x 2. That is 144 months he took to deposit that much. 144 / 12 months in a year is 12 years. He takes 12 years to save 144,000.00.

None of these are true.
Answers
Answer:
9a + 5b + 4 is written as a sum of three terms, 4 is a constant, 9a is a coefficient.
Step-by-step explanation:
A coefficient is the number before a letter. In some cases it would be the number you either multiply or divide by another number. A constant is a single number that either isn't changed or is added or subtracted by another coefficient (alone) . A term is just a mathematical expression used in math. It is either just a normal equation or a big expression like this one. You also cant add or subtract 9a by 5b or 4 because in order to to do that 5b or 4 has to have an "a" at the end~example- instead of 5b it would have to be 5a to subtract or add or do whatever . (has to be the same)
9a + 5b + 4 is written as a sum of three terms,
4 is a constant,
9a is a coefficient, (BUT SO IT 5b. they're both coefficient because they are with a variable opposed to 4 which is lonely with no variable by its side)
9a is a factor (a factor is one part of a product so i guess they would both be factors, same goes with 5b i think)
i'm not sure if i got any of there right but i hope i helped im some way!

▪︎Side 15 cm, 18 cm and x cm form a right angle triangle.
We know that :

Which means :
[tex] =\tt {15}^{2} + {x}^{2} = {18}^{2} [/tex]
[tex] =\tt 225 + {x}^{2} = 324[/tex]
[tex] =\tt {x}^{2} = 324 - 225[/tex]
[tex] = \tt {x}^{2} = 99[/tex]

You would like to start your own business in Hempstead. You borrow
$10,000 form the bank at a 9% rate for 5 years. How much interest
will you pay on this loan?
Answers
Answer:
$ 4,500.00
Step-by-step explanation:
I = $ 4,500.00
Equation:
I = Prt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 9%/100 = 0.09 per year,
then, solving our equation
I = 10000 × 0.09 × 5 = 4500
I = $ 4,500.00
The simple interest accumulated
on a principal of $ 10,000.00
at a rate of 9% per year
for 5 years is $ 4,500.00.
