The product of expression (3 + √7) (3 - √7) is, 2.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
We have to given that;
The expression is,
⇒ (3 + √7) (3 - √7)
Now, We can multiply the number as,
⇒ (3 + √7) (3 - √7)
⇒ (9 - 3√7 + 3√7 - 7)
⇒ 9 - 7
⇒ 2

Can someone help me with this question I will mark you brainliest if you get the correct answer. THANKS!! :))
Answer:
z = [tex]\frac{1}{5}[/tex], z = 3
Step-by-step explanation:
The absolute value function always returns a positive value.
However, the expression inside can be positive or negative, that is
5z - 8 = 7 ( add 8 to both sides )
5z = 15 ( divide both sides by 5 )
z = 3
OR
- (5z - 8) = 7
- 5z + 8 = 7 ( subtract 8 from both sides )
- 5z = - 1 ( divide both sides by - 5 )
z = [tex]\frac{1}{5}[/tex]
As a check
Substitute these values into the left side of the equation and if equal to the right side then they are the solutions
z = 3
left side = | 15 - 8 | = | 7 | = 7 = right side
z = [tex]\frac{1}{5}[/tex]
left side = | 1 - 8 | = | - 7 | = 7 = right side
Thus z = [tex]\frac{1}{5}[/tex], z = 3 are the solutions

Answer:
The answer is C.
[tex]n = 2t - 1[/tex]
Step-by-step explanation:
You can simply determind the answer by placing all pair of value n and t in the equation, one by one.
First, try the answer A, you should get as following;
[tex]n = t + 2 \\ 1 = 1 + 2[/tex]
and try to see if it is true or not,
in this case,
1 will never equal 1 + 2 (1 ≠ 1 + 2)
Therefore A is not the Answer. Try going through all other choices, and you will find the answer. The calculation is very simple, you probably won't need a calculator!

Answer:
Slope: 2
Y-intercept: (0,-7)
Step-by-step explanation:
2(x-3)=y+1
distribute the 2 through the parentheses
2x-6=y+1
2x+6=0+1
(change the y to 0)
2x-6=1
add 6 to both sides(+6 cancels out -6)
2x=1+6
divide both sides by 2
x=7/2 or x=3.5

The volume of a cube is 64 cubic inches. Which expression represents s, the length of a side of the cube?
Recall the formula Cube V = 5
s=/64
CS= 64 +64 +64
S= 64
S=64.64.64
Answer:
Therefore the length of a side of a cube is [tex]\sqrt[3]{64}\ or\ 4[/tex]Step-by-step explanation:
The volume of a cube is expressed as L³ where L is the length of each side of the cube.
Given volume of a cube = 64in³
On substituting;
64 = L³
Taking the cube root of both sides to determine L we have;
[tex]\sqrt[3]{64} = (\sqrt[3]{L})^{3}\\\sqrt[3]{64} = L\\L=4[/tex]
Therefore the length of a side of a cube is [tex]\sqrt[3]{64}\ or\ 4[/tex]
