Answer:
No. 5x and 5x² are not like terms.
When a variable is raised to two different powers, they can not be added together.
Another way to look at it is to note that:
5x + 5x² ≡ 5x(1 + x)
It is more obvious there that 1 and x are not like terms, thus neither are 5x and 5x², though they do have common factors.
Solve for b.
-t = 9(t - 10)
(WILL GIVE BRAINLIEST)
Answer:
Do you mean solve for t?
If you do, the answer is 9.
Step-by-step explanation:
If we expand the equation out, we get:
-t = 9t - 90
If we move the -90 over to the left side and the -t to the right side, we get:
90 = 10t
Dividing both sides by 9, we get:
t = 9
1. What is the area of a circle with a a diameter of 20 cm in terms of pi?
2. What is the area of a circle with a radius of a 8 yd using 3.14 as pi?
3. The area of a circle in terms of pi is 49pi. What is the radius of the circle?
Help needed and it would be appreciated
Answer:
1. 100pi cm
2. 200.96 yd
3. 7
Step-by-step explanation:
1.) diameter = radius multiple by two (D = r × 2)
&
radius = diameter divided by two (r = D ÷ 2)
So
20 ÷ 2 = 10 => A = pi (10)power 2 => A = 100pi
---------------------------------------------------------------------------------------------
2.) 3.14 × (8)power2 =200.96
---------------------------------------------------------------------------------------------
3.) A = 49pi => 49pi = pi(r)power2
[ cross out the pi from both sides]
And your left with
49 = (r)power2
[square root both sides to get rid of the power]
And your left with
7 = r

Use the expression 14x + 28y + 21
(Answer both questions below)
Part A: What is the greatest common factor of the expression?
Part B: Factor the expression
Answer:
A) 7 is the greatest common factor of the expression.
B) factoring the expression [tex]14x + 28y + 21[/tex] we get [tex]\mathbf{7(2x+4y+3)}[/tex]
Step-by-step explanation:
We are given the expression: [tex]14x + 28y + 21[/tex]
Part A: What is the greatest common factor of the expression?
We need to find the greatest common factor of the expression.
The expression is divisible by 7
So, 7 is the greatest common factor of the expression.
Part B: Factor the expression
We need to factor the expression: [tex]14x + 28y + 21[/tex]
Taking 7 common:
[tex]14x + 28y + 21\\=7(2x+4y+3)[/tex]
So, factoring the expression [tex]14x + 28y + 21[/tex] we get [tex]\mathbf{7(2x+4y+3)}[/tex]

Step-by-step explanation:
The video streaming service that you want to use is represented with the equation
below, where y represents the the total monthly cost of the service and x represents
the number of videos you plan to stream each month:
y = $1.25x + $5.00
Create a table for the values when x = 0, 5, 8, 10, 30
x-value
y-value
0
5
8
10
30
Answer:
HERES THE ANSWER
Step-by-step explanation:
0 = 5.00
5 = 11.25
8 = 15.00
10 = 17.50
30 = 42.50
also to understand it easier. # 1.25 times (whatever number), then take whatever that equals and add it to 5.00 ! (works for any question, just substitute the numbers)
To create a table for the values when x is given value, you can put those value in given function and can calculate what does y evaluates to.
The corresponding values of y are:
[tex]\begin{array}{cc}x&y\text{(In dollars)}\\0&5\\5&11.25\\8&15\\10&17.5\\30&42.5\end{array}\right[/tex]
Given that:y represents the total monthly cost to the servicex represents the number of videos you plan to stream each month. y = $1.25x + $5.00 ( a linear function )To find:Values of y for values of x as x = 0, 5, 8, 10, 30
Using the relation between y and x to find the values of y to corresponding values of x:For x = 0:[tex]y = 1.25x + 5\\ \\ y = 1.25x + 5|_{x=0}\\ y = 1.25 \times 0 + 5\\ y = \$5\\ \\ [/tex]
For x = 5:[tex]y = 1.25x + 5\\ \\ y = 1.25x + 5|_{x=5}\\ y = 1.25 \times 5 + 5\\ y = \$11.25\\ \\ [/tex]
For x = 8:[tex]y = 1.25x + 5\\ \\ y = 1.25x + 5|_{x=8}\\ y = 1.25 \times 8 + 5\\ y = \$15\\ \\ [/tex]
For x = 10:[tex]y = 1.25x + 5\\ \\ y = 1.25x + 5|_{x=10}\\ y = 1.25 \times 10 + 5\\ y = \$17.5\\ \\ [/tex]
For x = 30:[tex]y = 1.25x + 5\\ \\ y = 1.25x + 5|_{x=30}\\ y = 1.25 \times 30 + 5\\ y = \$42.5\\ \\ [/tex]
Thus, the corresponding values are:
[tex]\begin{array}{cc}x&y\text{(In dollars)}\\0&5\\5&11.25\\8&15\\10&17.5\\30&42.5\end{array}\right[/tex]

B. SAS
Step-by-step explanation:
In the given diagram, it would be observed that each side of the bigger triangle are multiplied by a factor of [tex]\frac{1}{3}[/tex] to give the values of each corresponding sides of the smaller triangle. But the included angle of the two triangles are the same.
Therefore, the reason why the triangles are similar is because of side-angle-side (SAS) relations. The correct option is B.

Answer:

3.110.41
Step-by-step explanation:
Answer:
Shape 1: 96.04
Shape 2: 110.41
Shape 3: 75.43
Step-by-step explanation:
For shape 1, you can do 9.8*9.8 and get the answer of 96.04. For shape 2, you can do 6.1*18.1 to get the answer of 110.41. Finally for shape 3, you can find the whole circle and divide it by 4 because it is only a quarter of the circle. The radius being 9.8, you then get the area of 301.72. But since its only a quarter of a circle you divide by 4 and get 75.43.
