Answer:
16. a = 13
Step-by-step explanation:
Equation: y = -4(-2) + 5
1) Multiply -4 with -2. Whenever you multiply two negatives, the product turn into a positive number; therefore, -4(-2) = 8
2) Then, add 8 and 5 which is 13.

What is 3(2x-4)=6(x-2)
with solving steps?
Answer:
true for all x
Step-by-step explanation:
3(2x-4)=6(x-2)
Distribute
6x - 12 = 6x -12
Subtract 6x from each side
6x-12 -6x = 6x-12-6x
-12 =-12
Since this is always true, there are infinite solutions
Answer:
The statement is true for any value of x, because both sides are identical.
Step-by-step explanation:
Step 1- Distribute into the parenthesis
(3)2x-(3)4=(6)x-(6)2
Step 2- Simplify the equation
6x-12=6x-12
Question:Choose the correct scale factor:
A)2
B)1/2
C)3
D)1/3
The length of ND = 3 units
The length of N'D' = 6
6 / 3 = 2
The scale factor is 2
Answer: A) 2
Step-by-step explanation:
The shape has been enlarge which means B and D are ruled out because if a shape gets enlarge its scale factor has to be greater than 1.
We will use the coordinate of the image of D to find the scale factor.
Pre-image: (2,2) Enlarge or image: (4,4)
So as we can see to get from 2 to 4 you will have to multiply by 2. So the scale factor is 2

Which expression is equivalent to (5m^)3
Answer:
5m•5m•5m
Step-by-step explanation:
You are multiply the factor by itself as many times as the exponent says. so if the factor is 5m, you would multiply it by itself by the exponent, which in our case is 3.
An expression is defined as a set of numbers, variables, and mathematical operations. The expression (5m)³ can be expressed as 5·5·5·m·m·m.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The given expression (5m)³ can be expressed in the following manner,
[tex](5m)^3 = 5 \cdot 5 \cdot 5\cdot m\cdot m\cdot m[/tex]
Hence, the expression (5m)³ can be expressed as 5·5·5·m·m·m.

The sum of Ymani and her mom’s ages is 54. If her mom is 30 years older than Ymani, how old is Ymani?
Answer:
Ymani is 12 years old.
Step-by-step explanation:
Y + M = 54
M = 54 - Y
Y + 30 = M
Y + 30 = 54 - Y
2Y = 24
Y = 12
Ymani is 12 years old.

Hi guys actually I have forgotten the steps do it yesterday my online school opened so I don't how to solve it can you help me please
Answer:
(i) (x +4)^3 = x^3 +12x^2 +48x +64
(ii) (2m +1)^3 = 8m^3 +12m^2 +6m +1
(iii) (a -2b)^3 = a^3 -6a^2b +12ab^2 -8b^3
Step-by-step explanation:
Powers of a binomial have a pattern. The coefficients of the terms of the expanded product are the numbers in the corresponding row of Pascal's Triangle. Here, you want the 3rd power, so the coefficients of interest are ...
1, 3, 3, 1
The pattern is ...
(a +b)^2 = a^2 +2ab +b^2
(a +b)^3 = a^3 +3a^2b +3ab^2 +b^3
The total of powers of the variable is equal to the exponent of the binomial. The powers of the first variable decrease to 0 while the powers of the second variable increase from zero.
When 'a' or 'b' is something with a coefficient, that whole term is raised to the appropriate power.

The numbers in each row are the sums of the two numbers immediately above. For binomial expansion, you're only interested in the contents of a row. The "patterns" shown in the attachment are an extra added attraction, not particularly relevant to binomial expansion.

It is clear from the diagram that,
ㄥ6 + ㄥ8 = 180⇒ (2x - 5) + (x + 5) = 180
⇒ (2x + x) + (5 - 5) = 180
⇒ 3x + 0 = 180
⇒ x = 180/3
⇒ x = 60°
◈ From the geometry of figure,
ㄥ3 = ㄥ6⇒ ㄥ6 = (2x - 5)
⇒ ㄥ6 = (2×60 - 5)
⇒ ㄥ6 = 120 - 5
⇒ ㄥ6 = 115°

6*4+2 / 2-7
1: 20+2 / 2-7

3: 21-7
14
In this equation we need to use OoO ( order of operations) Or Pemdas!
The first step seince there arnt any exponents or parenthesies we need to multiply 6*4=20 Next we need to divide 2 by 2 wich is 1. Now that we got multiplication and divition done we add 10+1 wich is 21. Last but not least wesubtract 21 by 7= 14 Therefor the awnser is 14!
Sandy didnt follow Pemdas and she did not go from left to right. She added and did not divide on step one and on step 2. All the other steps are right sandy messed up on step 1. Therfore sandy got a difrent awnser than she was soupossed to.

Type the correct answer in the box. Use numerals instead of words. The height of a baseball, in feet, is represented by this expression, where t is time in seconds.
Answer:
31 feet.
Step-by-step explanation:
It is mentioned in the question that
Height of baseball expressed in feet
T = time in seconds
Also
[tex]h= -16t^2+64t+3[/tex]
Now the time is 3.5 so put this value to the above equation
h = -16(3.5)^2 + 64(3.5) + 3
= -16(2.25) + 224 + 3
= -196 + 227
= 31
Therefore the height of a baseball is 31 feet and the same is to be considered
Caroline drives 37.5 miles in 30 minutes. If she drove three hours in total at the same rate, how far did she go?
Hey there! I'm happy to help!
3 hours is 180 minutes as there are 60 minutes in 1 hour. How many times does 30 minutes go into 180 minutes?
180/30=6
So, we have six of these 30 minute time slots that fit into 3 hours. So, we multiply our 37.5 miles by six to find the total mileage!
37.5×6=225
Caroline drove 225 miles.

A moving truck has a length that measures 10 ft, a width of 6 ft,
and a height of 61, Ft. What is the volume of the
moving truck?
Answer:
3660 ft^3
Step-by-step explanation:
Answer:
the volume of the truck = 390 ft³
Step-by-step explanation:
given:
Length that measures 10 ft, a width of 6 ft,
and a height of 6 1/2, Ft.
find:
What is the volume of the
moving truck?
volume of a rectangular prism = L x W x H
where L = length = 10 ft.
W = width = 6 ft.
H = height = 6 1/2 ft
plugin values into the formula:
V = 10 x 6 x 6.5
V = 390 ft³
therefore,
the volume of the truck = 390 ft³
