Answer:
2x^2 + 23
Step-by-step explanation:
For this problem, we will simply combine like terms after using the distributive property:
7x^2 + 3 - 5(x^2 - 4)
= 7x^2 + 3 - 5x^2 + 20
= 7x^2 - 5x^2 + 3 + 20
= 2x^2 + 23
Cheers.

What is the quotient of 9.5 divided by 2
the answer is 4.6 because I divided it
The quotient of the division are solved and A = 9.5/2 = 4.75
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the numerator of the fraction be p
where the value of p = 9.5
Let the denominator of the fraction be q
where q = 2
Now , the fraction is A = p/q
On simplifying the expression , we get
So , the left hand side of the equation is equated to the right hand side by the value of p/q
A = 9.5/2
On further simplification , we get
A = 4.75
Therefore , the value of A = 4.75
Hence , the fraction is A = 4.75

Which decimal is equivalent to 56?
Answer:
0.56
Step-by-step explanation:
Find the value of each variable (x in this case)
2x and 4x + 108 are supplementary angles and that means they add up to 180 degrees.
2x + 4x + 108 = 180
Combine like terms
6x + 108 = 180
Subtract 108 from both sides.
6x = 72
Divide both sides by 6
x = 12

The value of the x is 8 if after using the property of a similar triangle.
What is the similarity law for triangles?
It is defined as the law to prove that the two triangles have the same shape, but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same proportions and the corresponding angles are congruent.
We have a triangle shown in the picture.
By using the property of a similar triangle:
2/1 = 14/(2x-9)
2x - 9 = 7
2x = 7 + 9
2x = 16
x = 8
Thus, the value of the x is 8 if after using the property of a similar triangle.

The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
Here sum = 75, mean = 15 and let n be count, thus
[tex]\frac{75}{n}[/tex] = 15 ( multiply both sides by n )
75 = 15n ( divide both sides by 15 )

The height of a tree is 38 inches. After 4 years, the height is 9 feet 10 inches. How many inches did the tree grow each year?
The tree grows linearly, then the tree grows each year will be 20 inches.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
The height of a tree is 38 inches.
After 4 years, the height is 9 feet 10 inches.
1 ft = 12 inches
9 ft = 180 inches
Then 9 ft and 10 inches will be
→ 108 + 10
→ 118 inches
The tree grows in 4 years and will be
→ 118 - 38
→ 80 inches
Let the tree grows linearly, then the tree grows each year will be
→ 80 / 4
→ 20 inches
