Answer:
-16
Step-by-step explanation:
(X + Y)
= (-3 + -5)
= -8
(X - Y)
= (-3 - -5)
= 2
Because they're still in brackets in this form:
(-8) (2)
You multiply them both and you'll get the answer:
-16

PLEASE HELP!!! Area of trapezoids and triangles
Answer: 54 square inches and 18 square inches
Explanation:
The formula for the area of a trapezoid is the sum of the top and bottom bases divided by 2, multiplied by the height.
In the first picture the bases are 6 and 12, and the height is 6, so the formula would look like this:
[tex]\frac{6+12}{2} *6[/tex]
=[tex]\frac{18}{2} *6[/tex]
=[tex]9*6[/tex]
=54
54 [tex]in.^{2}[/tex] is the answer to the first problem.
Following the same method, we can do the next problem the same way:
[tex]\frac{4+8}{2} *3[/tex]
=[tex]\frac{12}{2} *3[/tex]
=[tex]6*3[/tex]
=18
18 [tex]in.^{2}[/tex] is the answer to the second problem.

Craig wants to put molding around the edge of a rectangular frame that is 8 inches wide and 14 inches long. The molding costs $0.75 per inch. He buys 3 additional inches of molding. What is the total cost?
11.25
25.75
35.25
84.75
please explain your work
Answer:
$35.25
Step-by-step explanation:
Find the total number of inches needed.
The rectangle has 2 sides of 8 inches and 2 sides of 14 inches.
8 + 8 + 14 + 14 = 44 inches
he also was an additional 3 inches
44 + 3 = 47
Now we can find the total price
47 inches × $0.75 = $35.25

Many golfers wear wrist bracelets containing magnets because they claim the magnets improve balance and the length of shots played off the tee. A golfer would like to determine if the claim has merit and plans to collect data on the length of shots played by golfers who use the magnetic bracelets. Another golfer points out that many golfers who purchase the bracelets also purchase other expensive golf equipment, such as golf clubs, and this could be a confounding variable.
Which statement best describes the effect of the confounding variable?
A. Because golfers purchase expensive golf clubs, they may stop wearing their magnetic bracelets, which would interfere with the outcome of the study.
B. Because golfers can be randomly assigned to receive either magnetic bracelets or expensive golf clubs, the expensive golf clubs are a confounding variable.
C. Because golfers using the magnetic bracelets believe they are hitting longer shots, the study may show their shots are not as long as they believe.
D. Because golfers may use both magnetic bracelets and expensive golf clubs, it will be difficult to determine which variable contributes most to longer shots.
Answer:
d
Step-by-step explanation:
just made a 100
The statement "Because golfers may use both magnetic bracelets and expensive golf clubs, it will be difficult to determine which variable contributes most to longer shots." best describes the confounding variable.
What is a confounding variable?A confounding variable is a third variable used to examine research based on a cause and effect relationship.
Golfers who are likely to use the magnetic bracelets also buy and use other expensive golf equipment. This means that it would be difficult to determine whether the bracelet is having any effect on the performance of the golfers. The effect of the expensive equipment will hinder the results of the study.Therefore, we have determined that statement D "Because golfers may use both magnetic bracelets and expensive golf clubs, it will be difficult to determine which variable contributes most to longer shots." best describes the effect of the confounding variable.

Whats the answer for 7/9 - 4/9 in fraction in number
Answer:
3/9
Step-by-step explanation:
numerator:7-4=3/9
The subtraction of the the fraction 7/9 -4/6 results to 1/3.
Given Fraction:
7/9 - 4/9
To subtract fractions, have a common denominator.
In this case, both fractions already have the same denominator of 9,
Now, subtract the numerators as:
= 7/9 - 4/9
= (7 - 4)/9
= 3/9
By dividing both the numerator and denominator by 3 gives
3/9 = 1/3
So, the answer to 7/9 - 4/9 as a simplified fraction is 1/3.

Which graph represents an exponential function?
write the inequality shown -4x+y=-3
The inequality corresponding to the equation -4x + y = -3 is either y > 4x - 3 or y < 4x - 3, depending on the relationship between 4x - 3 and 0.
To write the inequality represented by the equation -4x + y = -3, we first need to manipulate the equation to express y in terms of x.
Starting with -4x + y = -3, we isolate y by adding 4x to both sides:
y = 4x - 3
Now we have y expressed in terms of x. To form the inequality, we consider the relationship between x and y. The inequality depends on whether the expression 4x - 3 is greater than or less than 0.
If 4x - 3 is greater than 0, then y is greater than 0, and we can write the inequality as:
y > 4x - 3
If 4x - 3 is less than 0, then y is less than 0, and we can write the inequality as:
y < 4x - 3
The inequality represents a region in the coordinate plane where the y-values are either greater than or less than the expression 4x - 3, depending on the direction of the inequality sign.
For example, if we choose a point (x, y) in the region above the line y = 4x - 3, where y is greater than 4x - 3, the inequality y > 4x - 3 will hold true. On the other hand, if we choose a point below the line, where y is less than 4x - 3, the inequality y < 4x - 3 will be satisfied.
