14. Which special product is represented by: (5a? - 7b)??
a. Product of Two Binomials
c. Cube of a Binomial
b. Square of a Binomial
d. Product of a Binomial and a Trinomial
Answer:
[tex]A=2x^2+3x-5[/tex]
Step-by-step explanation:
Given that,
Length = (2x+5) cm
Width = (x-1) cm
We need to find the area of a rectangle. The formula for the area of rectangle is given by :
A = lb
[tex]A=(2x+5)(x-1)\\\\=2x^2-2x+5x-5\\\\=2x^2+3x-5[/tex]
So, the required area is equal to [tex]2x^2+3x-5[/tex].

B and C represent it.
Step-by-step explanation:
If Andre babysat 5 times and earned the same amount each time then it would be represented by the five rectangles with W on them.
If Andre got a $4 tip at the end of the month then it would be represented by the small 4 rectangle at the end.
If Andre made a total of 99 dollars then the large grouping 99 at the top would represent that.
If a family of 5 went to a concert in which all tickets costed the same then it would be represented by the five rectangles with W on them.
If they paid $4 for parking then it would be represented by the small 4 rectangle at the end.
If they spent a total of 99 dollars then the large grouping 99 at the top would represent that.
Over what interval is the function in this graph increasing?
Answer:
the function is increasing on (-4, 1)
Step-by-step explanation:
First the graph descends (drops), until it reaches x = -4. Then the graph rises, until x = 1. Thus, we say "the function is increasing on (-4, 1)."
Given the function f(x) = 2 x + 61 - 4, for what values of x is f(x) = 6?
O x= -1, x = 11
Ox=-1, x = -11
O x= 14 = -26
O x= 26, x=-14
Answer:
[tex]x = -1[/tex] or [tex]x = -11[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 2|x+6| - 4[/tex]
Required
Find x when
[tex]f(x) = 6[/tex]
Substitute 6 for f(x)
[tex]6 = 2|x+6| - 4[/tex]
Add 4 to both sides
[tex]4+6 = 2|x+6| - 4+4[/tex]
[tex]10 = 2|x+6|[/tex]
Divide both sides by 2
[tex]5 = |x + 6|[/tex]
Rewrite as:
[tex]|x + 6| = 5[/tex]
This can be split to:
[tex]x + 6 = 5[/tex] or [tex]-(x + 6)=5[/tex]
Solve for x in both cases
[tex]x = 5 - 6[/tex] or [tex]x + 6 = -5[/tex]
[tex]x = -1[/tex] or [tex]x = -6 - 5[/tex]
[tex]x = -1[/tex] or [tex]x = -11[/tex]
Answer:
i think it’s x= -1, x = -11

Round to the nearest hundredth:7.884
Answer:
7.88
Step-by-step explanation:
Hope this helps :D
When rounding to the nearest hundredth, the number 7.884 becomes 7.88.
To round 7.884 to the nearest hundredth, we look at the digit in the thousandth place, which is 8.
Now, If the digit to the right is less than 5, you simply drop all the digits to the right and keep the desired decimal place unchanged.
If the digit to the right is 5 or greater, you round up the desired decimal place by increasing it by one. Drop all the digits to the right.
Since 8 is greater than or equal to 5, we round up the digit in the hundredth place.
Therefore, when rounding to the nearest hundredth, the number 7.884 becomes 7.88.

Keith leaves a 15% for a dinner bill of $25. What amount of tip does Keith leave? $ What is the total bill? $
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that Keith leaves a 15% for a dinner bill of $25. The amount of tip that Keith leaves will be calculated by multiplying 15% by $25. This will be:
= 15% × $25
= 15/100 × $25
= 0.15 × $25
= $3.75
Keith's total bill will be gotten by adding the dinner bill plus the tip together. This will be:
= $25 + $3.75
= $28.75

Answer:
x=10.58
Step-by-step explanation:
To find the side length of a right triangle, you can use the Pythagorean theorem.
The Pythagorean theorem is [tex]a^2+b^2=c^2[/tex]
the c is the hypotenuse of the triangle, so 16.
the a and b are the other sides of the triangle, so x and 12.
Therefore, [tex]x^2+12^2=16^2[/tex]
now you can solve the equation.
[tex]x^2+144=256[/tex]
-144 -144
[tex]x^2=112[/tex]
now you have to square root both sides of the equation.
[tex]\sqrt{x^2} =\sqrt{112}[/tex]
x=10.58
