Answer:
length = 50 cm
Step-by-step explanation:
let width be w then length = w + 10
area = w(w + 10) = 2000 , that is
w² + 10w = 2000 ( subtract 2000 from both sides )
w² + 10w - 2000 = 0 ← in standard form
Consider the factors of the constant term (- 2000 ) which sum to give the coefficient of the w- term ( + 10)
the factors are + 50 and - 40 , since
50 × - 40 = - 2000 and sum = 50 - 40 = + 10
(w + 50)(w - 40) = 0 ← in factored form
equate each factor to zero and solve for w
w + 50 = 0 ⇒ w = - 50
w - 40 = 0 ⇒ w = 40
Since w > 0 then w = 40 and
length = w + 10 = 40 + 10 = 50 cm

use the zero and the labeled point to write the quadratic function represented by the graph.
A.y=x^2-2x-8
B. y=2x^2-12x+16
C. y=x^2+2x-8
D. y=2x^2+4x-16
Answer:
A. x² - 2x - 8
Step-by-step explanation:
At x = -2, 4 graph cut x- axis. So, they are zeroes of f(x).
So, f(x) = k(x+2)(x-4), where k is a constant.
Now, (3, -5) in f(x), we get
-5 = k (3+2)( 3 -4)
-5 = -5k
k= 1
So, f(x) = (x+2)(x-4)
= x² - 2x - 8

A sporting goods store sells square exercise mats that are 17 m on a side. Find the perimeter and area of the mat.
Answer:
Permeter= 68m
Area= 289m^2
Step-by-step explanation:
Perimeter = 17^4 = 68m cause perimeter is the total length and square has 4 sides
Area= 17 ^17= 289m^2
Area of square is to multiply length x length
The perimeter and area of the mat will be 68 meters and 289 square meters.
What is the area and perimeter of the square?All the sides of a square are congruent. Let a be the side length of the square. Then the area of the square is the square of the side length of the square.
The area of the square will be
A = a² square units
The sum of all the sides of the square will be known as the perimeter of the square.
The perimeter of the square will be
P = 4a units
A sporting goods store sells square exercise mats that are 17 m on a side.
The area of the square will be
A = 17²
A = 289 square meters
The perimeter of the square will be
P = 4 x 17
P = 68 meters
The perimeter and area of the mat will be 68 meters and 289 square meters.

Answer:
m= 12
Step-by-step explanation:
[tex]\frac{3m+4}{8} = 5[/tex]
First multiply both sides by 8 to cancel out the 8 on the left side
[tex]3m + 4 = 80[/tex]
Isolate the m so subtract 4 from both sides.
[tex]3m = 36[/tex]
Divide both sides by 3.

You have Pennies and nickles that are equal to $8.80. You have twice the number of nickles than Pennies. Write an equation for this problem. How many nickles do you have and how many Pennies do you have?
Answer:
Step-by-step explanation:
Let's set up the variables as nickel=n and penny=p, for how many coins he has of each type. What we know is that Calvin had $8.80 total and that he has twice as many nickels as pennies. So, one equation for his total money and another for how many separate coins: 8.80 = 0.01p + 0.05n 2p=n

In the year 2003, a company made $6.5 million in profit. For each consecutive year after that, their profit increased by 8%. How much would the company's profit be in the year 2007, to the nearest tenth of a million dollars?
Answer:
$8,580,000 (rounded) = $9,000,000

Yolanda makes $11.25 per hour at her part-time job. During one week, she worked 1225 hours and also earned some tips. Her final pay for the week was $159.50.
How much money did Yolanda earn in tips?
Answer:
she earned $20 in tips
Step-by-step explanation:
- figure out how much she'll get payed in 12 hours of work, :
12 x $11.25 = $135 for 12 hours work, then find out 2/5 of $11.25 to find out how much she would get for the 2/5 of an hour she worked:
2/5 of $11.25 = $4.50, after all of that, add up both of these sums together to get her total pay for hours worked:
$135 + $4.50 = $139.50
now you need to subtract that sum from her total pay to find out how much money she earned in tips:
$159.50 - $139.50 = $20, so basically thats how i got 20.
