Answer:
Shauna is incorrect, because (x + 4)(x - 3) is NOT equivalent to 2x² + x - 12
Step-by-step explanation:
Check if she is correct by expanding (x + 4)(x - 3), with FOIL:
(x + 4)(x - 3)
x² - 3x + 4x - 12
x² + x - 12
So, Shauna is incorrect, because the two expressions are not equal.
(x + 4)(x - 3) is equivalent to x² + x - 12, NOT 2x² + x - 12.
Answer:
No she's wrongTwo equations are unequal.Explained belowStep-by-step explanation:
[tex] \sf \rightarrowtail \: (x + 4)(x - 3) \\ \sf \rightarrowtail \: x(x - 3) + 4(x - 3) \\ \sf \rightarrowtail \: {x}^{2} - 3x + 4x - 12 \\ \sf \rightarrowtail \: {x}^{2} + x - 12 \cancel{ = } {2x}^{2} + x - 12[/tex]

B)How many students were not majoring in computer science?
C) how many students were not math or computer science majors?
Answer:
Use n(u) formula of chapter sets
Step-by-step explanation:
Have a good day
11 students were majoring in math only; 13 students were not majoring in computer science; and 2 students were not math or computer science majors.
Given that in a class of 25 students, 18 were math majors, 12 were computer science majors, and 7 were dual majors in math and computer science, to determine A) how many students were majoring in math only; B) how many students were not majoring in computer science; and C) how many students were not math or computer science majors; the following calculation must be performed:
Math majors only = 18 - 7 = 11 Not majoring in computer science = 25 - 12 = 13 Not math or computer science majors = 25 - 7 - 11 - (12 - 7) = 18 - 11 - 5 = 2
Therefore, 11 students were majoring in math only; 13 students were not majoring in computer science; and 2 students were not math or computer science majors.

Given:
The expression is:

To find:
The simplified form of the given expression.
Solution:
We have,
[tex]-6\dfrac{1}{4}-2\dfrac{1}{8}[/tex]
Write the mixed fractions in the form of improper fractions.
[tex]=-\dfrac{6(4)+1}{4}-\dfrac{2(8)+1}{8}[/tex]
[tex]=-\dfrac{24+1}{4}-\dfrac{16+1}{8}[/tex]
[tex]=-\dfrac{25}{4}-\dfrac{17}{8}[/tex]
Taking LCM, we get
[tex]=\dfrac{2(-25)-17}{8}[/tex]
[tex]=\dfrac{-50-17}{8}[/tex]
[tex]=\dfrac{-67}{8}[/tex]
Now write this improper fraction in the form of mixed fraction.
[tex]=-\dfrac{64+3}{8}[/tex]
[tex]=-\left(\dfrac{64}{8}+\dfrac{3}{8}\right)[/tex]
[tex]=-\left(8+\dfrac{3}{8}\right)[/tex]

Answer:
11x11 inches
Step-by-step explanation:
You are missing the first part of the problem, which is the following:
"Miriam reduced a square photo by cutting 3 inches away from the length and the width so it will fit in her photo album. The area of the reduced photo is 64 square inches. In the equation (x – 3)2 = 64, x represents the side measure of the original photo. What were the dimensions of the original photo?"
With this in mind, we just need to solve the equation and determine the value of x. The equation is:
(x - 3)² = 64
Solving this, we have:
x - 3 = √64
x - 3 = 8
x = 8 + 3
x = 11Therefore, we can conclude that the original dimensions of the photo are 11x11 inches.

A mattress store is having a sale all mattresses are 30% of. Nate wants to know the sale price of a mattress that is regularly $1,000
Answer: $700
Step-by-step explanation:
The store is selling at 30% off.
If a mattress is $1,000, first find out what 30% of $1,000 is:
= 1,000 * 30%
= $300
The store is selling 30% off, this means that they are reducing the price by 30%:
= 1,000 - 300
= $700
