Answer:
The lengths of the sides of the rectangle are 13 inches and 15 inches
Step-by-step explanation:
The perimeter of a rectangle
Given the two sides of a rectangle a and b. The perimeter of the rectangle is:
[tex]P=2(a+b)[/tex]
We are given the perimeter of a rectangle as:
[tex]P=8(2x+1)[/tex]
And each side has a length of 3x+4 and 4x+3. Calculating the perimeter:
[tex]P=2(3x+4+4x+3)=2(7x+7)[/tex]
We set up the equation:
[tex]8(2x+1)=2(7x+7)[/tex]
Dividing by 2:
[tex]4(2x+1)=7x+7[/tex]
Operating:
[tex]8x+4=7x+7[/tex]
Subtracting 7x:
[tex]x+4=7[/tex]
Subtracting 4:
x=3
The length of each side is:
3x+4=3*3+4=13
4x+3=4*3+3=15
The lengths of the sides of the rectangle are 13 inches and 15 inches

Which shows the equation in slope-intercept form of a line with a slope of 4 and a y-intercept of -5?
Answer:
y = 4x - 5
Step-by-step explanation:
Slope-intercept form: y = mx + b
m = slope
b = y-intercept
Since 4 is the slope and -5 is the y-intercept we will substitute it for m for the slope and -5 for the b.
y = 4x + (-5)
y = 4x - 5
A ball is thrown directly upward from a height of 7 ft with an initial velocity of 20 ft/sec. The function s(t)-16tsquared plus 20t plus 7 gives the height of the ball, in feet, t seconds after it has been thrown. Determine the time at which the ball reaches its maximum height and find the maximum height.
Last year, Norman made 10 free trows per game.This year he makes 12 free trows per game.What percent increase in the number of free trows he makes this year.
Answer:
20%
Step-by-step explanation:
Given that:
Last year : number of free throws per game = 10
This year ; number of free throws per game = 12
Percentage increase in the Number of free throws he makes this year:
[(this year - last year) / last year] × 100%
[(12 - 10) / 10] * 100%
(2 / 10) * 100%
0.2 * 100%
20%
Hence, there was a 20% increase in the Number of free throws made this year.

How many solutions does the equation 2 (p+ 7) = 4 - 8p have?
A.One solution
B.Infinitely Many Solutions
C.No Solution
Answer:
one solution p=-1
Step-by-step explanation:
The equation 2 (p+ 7) = 4 - 8p has only one solution which is -9.
What is the solution for an equation?The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of that variable would give a true mathematical statement.
We need to find the solutions does the equation 2 (p+ 7) = 4 - 8p have;
Now solving for p;
2 (p+ 7) = 4 - 8
Open the bracket;
2p+ 14 = 4 - 8
Combine the like terms;
2p = -4 - 14
2p = -18
p = -18/2 = -9
Therefore, the equation 2 (p+ 7) = 4 - 8p has only one solution which is -9.

$11.25
$90.00
$86.25
$75.15
Answer:
C

Scrieti fiecare dintre nr 24, 36 si 60 ca: a) produs de 2 factori, diferiti de 1 b) produs de 3 factori, diferiti de 1 c) produs de cat mai multi factori, diferiti de 1
Answer:
Step-by-step explanation:
1. Produse cu 2 factori
24 = 4 * 6
36 = 3 * 12
60 = 6 * 10
2. Produs de 3 factori
24 = 2 * 3 * 4
36 = 2 * 3 * 6
60 = 2 * 3 * 10
3. Cât mai mulți factori posibil
24 = 2 * 2 * 2 * 3
36 = 2 * 2 * 3 * 3
60 = 2 * 2 * 3 * 5
