the answer is A.
<em>Credit markets increase in a strong economy, and with increased demand come increased prices.</em>
Step-by-step explanation:
The mean basically means the average number between all numbers given. You can find the mean by adding them together and diving by the number of numbers. In this case, 12 + 24 + 24 + 52= 112.
<span>Simplifying
4(x + -3) = 7x + 24
Reorder the terms:
4(-3 + x) = 7x + 24
(-3 * 4 + x * 4) = 7x + 24
(-12 + 4x) = 7x + 24
Reorder the terms:
-12 + 4x = 24 + 7x
Solving
-12 + 4x = 24 + 7x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7x' to each side of the equation.
-12 + 4x + -7x = 24 + 7x + -7x
Combine like terms: 4x + -7x = -3x
-12 + -3x = 24 + 7x + -7x
Combine like terms: 7x + -7x = 0
-12 + -3x = 24 + 0
-12 + -3x = 24
Add '12' to each side of the equation.
-12 + 12 + -3x = 24 + 12
Combine like terms:
-12 + 12 = 0
0 + -3x = 24 + 12
-3x = 24 + 12
Combine like terms: 24 + 12 = 36
-3x = 36
Divide each side by '-3'.
x = -12
Simplifying
x = -12</span>
Answer:
on my screen it sayes its 50938
Step-by-step explanation:
Given expression is x² - 121
This is called Difference of Squared terms, we have a formula that is given as :-
a² - b² = (a - b) · (a + b)
Now using the above formula in the given expression, we get :-
x² - 121
x² - (11)²
here a = x and b = 11
x² - (11)² = (x - 11) · (x + 11)
but it says that student gave the answer as (x - 11) · (x - 11).
So, student's answer should be (x - 11) · (x + 11) instead of product of two (x - 11) terms.
