3x * 3x = 9x^2
3x * 5 = 15x
-5 * 3x = - 15x
-5 * 5 = - 25
Notice the 2nd and 3rd terms. They are equal except that one is plus and the other minus. That means they cancel. You are left with
9x^2 - 25
The length and width of a rectangle are shown below.
50 X
2x+10
Please hurry
The expression -2x² + 90x +500 represents the area of the rectangle if the length and width of the rectangle are (50 - x) and (2x + 10) option (c) is correct.
What is the area of the rectangle?It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
Area of rectangle = (50 - x)(2x+10)
[tex]\rm -2x^2+90x+500[/tex]
Thus, the expression -2x² + 90x +500 represents the area of the rectangle if the length and width of the rectangle are (50 - x) and (2x + 10) option (c) is correct.

3/4 + (1/3 divided by 1/6) - (-1/2) = ?
Iready diagnostics.
Answer: 13/4
Step-by-step explanation:
First you have to solve the equation in the parenthesis.
1/3 divided by 1/6 = 2
3/4 + 2 = 11/4 or in decimal form: 2.75
11/4 - (-1/2) btw... the subtraction and the negative together cancel out and become addition.
11/4 + 1/2 = 13/4 or in decimal form 3.25
Answer:
13/4
Step-by-step explanation:
Q:-3/4+(1/3 ÷1/6)-(-1/2)
A:-3/4+(1/3×6/1)+1/2
=3/4+2+1/2
=3+2/4 +2
=5/4+2
=5+8/4

Graph the relationship from Exercise 5.
Part B
Maria has $3,000 in the bank, has a home worth $150,000, and has a $75,000 home loan. She also has $10,000 in Investments and a $15,000
student loan. What is Maria's net worth? Show your work please
Answer:
$73,000
Step-by-step explanation:
To answer, you simply subtract and add numbers along the way. First, because Maria has money in the bank and her home is worth money, we add those numbers together:
3,000 + 150,000 = 153,000
Now, because she has a home loan, that means she owes money, so you subtract that from her net worth so far:
153,000 - 75,000 = 78,000
Her investments money would be added:
78,000 + 10,000 = 88,000
And another student loan would be subtracted:
88,000 - 15,000 = 73,000
So, Maria's net worth is $73,000

Simplify the expression ( 6x3-5x) + (2x3 + x 2+ 10x).
Answer:
see below
Step-by-step explanation:
I assume when you write x3 you mean
[tex] {x}^{3} [/tex]
so the expressions is:
[tex](6{x}^{3} - 5x) + (2 {x}^{3} + {x}^{2 } + 10x)[/tex]
we can combine like terms
[tex]6 {x}^{3} + 2 {x}^{3} + {x}^{2} - 5x + 10x[/tex]
[tex]8 {x}^{3} + {x}^{2} + 5x[/tex]
the last thing we can do is factor out x because all 3 pieces have at least one x in them
[tex]x( 8{x}^{2} + x + 5)[/tex]

Karla rode her bicycle 135 miles in 9 weeks, riding the same distance each week. Brad rode his bicycle 102 miles in 6 weeks, riding the same distance each week. Which statement correctly compares the number of miles per week they rode?
Answer:
Karla's 15 miles per week to Brad's 17 miles per week.
Step-by-step explanation:
First, we would need find the total number of miles each individual rides per week. We do this by dividing the total miles ridden by the number of weeks it took for each individual like so...
Karla: 135 / 9 = 15 miles per week
Brad: 102 / 6 = 17 miles per week
Finally, the comparison would be
Karla's 15 miles per week to Brad's 17 miles per week.
Answer:
Eric rode 2 more miles per week than Kim rode

A point P(x,y) is shown on the unit circle corresponding to a real number t. Find the values of the trigonometric functions at t. The point P is (√10/10 , -3√10/10)
sin t=
cos t=
tan t=
csc t=
sec t=
cot t=
Answer:
Step-by-step explanation:
sin(t) = -3√10/10
cos(t) = √10/10
tan(t) = sin(t)/cos(t) = -3
csc(t) = 1/sin(t) = -√10/3
sec(t) = 1/cos(t) = √10
cot(t) = 1/tan(t) = -⅓
