The dimensions of the paint, obtained by factoring the polynomial function for the area of the tray, 42·x + 135·x + 108 are as follows;
(a) The width of the tray = 6·x + 9
(b) Area of the square paint compartment is 9 in²
(c) The width of the edges is 12 inches
What are the factors of a polynomial?The factors of a polynomial are other polynomials of lesser degree, that when multiplied together, produces the polynomial which is factored.
The area of the paint tray = 42·x² + 135·x + 108 in²
The dimensions of the square paint compartment are the same
Space along the edge of the tray = 2 × space between the squares
(a) The length of the tray obtained from the diagram in the question = 7·x + 12 inches
Using an online tool, we get;
42·x² + 135·x + 108 = 3·(2·x + 3)·(7·x + 12)
The area of a rectangle = Length × Width
Therefore, the width of the tray = The area ÷ The length
Width = (42·x² + 135·x + 108)/(7·x + 12) = 3·(2·x + 3)
The width of the tray = 3·(2·x + 3) = 6·x + 9(b) Let s represent the side length of each square paint compartment, we get;
Width of four compartments + 3 spaces between compartments = (7·x + 12) - 2 × 2·x
Width of four compartments + 3 spaces between compartments = 4·s + 3·x
4·s + 3·x = (7·x + 12) - 2 × 2·x = 3·x + 12
4·s = 3·x + 12 - 3·x = 12
s = 12/4 = 3
s = 3
The side length of each square = 3 inches
The area of each square paint compartment = s²
s² = 3² = 9
The area of each square paint compartment = 9 square inches(c) Where the width = 45 inches, we get;
3·(2·x + 3) = 45
2·x + 3 = 45/3 = 15
2·x + 3 = 15
2·x = 15 - 3 = 12
x = 12/2 = 6
x = 6
The width of the edges of the tray = 2·x
2·x = 2 × 6 = 12
The width of the edges of the tray = 12 inches

After seling 15 lemonades. Jessicamade $5. After seling 42 lemonades, she
made $18.50. Write and solve an equation to find how much Jessica spent
on supples.
Answer:Let x be the number of full cup sold Let y be the number of half cup sold Whether the cup was full or not, they used 37 cups. Therefore, x + y = 37 How much money did they make selling half cup lemonade? They made y × 0.25 How much money did they make selling full cup lemonade? They made x × 0.50 Money made selling full cup + money made selling half cup = 15 x × 0.50 + y × 0.25 = 17 You end up with a system of linear equation to solved x + y = 37 x × 0.50 + y × 0.25 = 17 x + y = 37 equation 1 0.50x + 0.25y = 17 equation 2 Solve for y in equation 1 x + y = 37 x - x + y = 37 - x y = 37 - x Replace y in equation 2 0.50x + 0.25 (37 - x) = 17 0.50x + 0.25 × 37 - 0.25x = 17 0.50x + 9.25 - 0.25x = 17 0.25x + 9.25 = 17 0.25x + 9.25 - 9.25 = 17 - 9.25 0.25x = 17 - 9.25 0.25x = 7.75 Divide both sides by 0.25 0.25x/0.25 = 7.75/0.25 x = 31 y = 37 - x = 37 - 31 = 6 Sasha and Francisco sold 31 full cup and 6 half cup of lemonade It seems like people love their lemonade

a straight line has equation 4y-5x=2 work out the gradient of this line
Answer:
gradient = [tex]\frac{5}{4}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope (gradient) and c the y- intercept )
Given
4y - 5x = 2 ( add 5x to both sides )
4y = 5x + 2 ( divide the terms by 4 )
y = [tex]\frac{5}{4}[/tex] x + [tex]\frac{1}{2}[/tex] ← in slope- intercept form
with gradient m = [tex]\frac{5}{4}[/tex]

If x and y vary directly and x=25 when y=100 find x when y=24.
PLEASE HELP FASTTTTTTT
Answer:
x = 6
Step-by-step explanation:
Given that x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 25 when y = 100 , then
100 = 25k ( divide both sides by 25 )
4 = k
y = 4x ← equation of variation
When y = 24 , then
24 = 4x ( divide both sides by 4 )

5 Which equation is equivalent to
3(2 x – 5) = 4( x + 3)?
A 2x= -27
B 2 x= 27
C 10 x=-27
D 10 x=-3
Answer:
I think its B
Step-by-step explanation:
Let's solve your equation step-by-step.
3(2x−5)=4(x+3)
Step 1: Simplify both sides of the equation.
3(2x−5)=4(x+3)
(3)(2x)+(3)(−5)=(4)(x)+(4)(3)(Distribute)
6x+−15=4x+12
6x−15=4x+12
Step 2: Subtract 4x from both sides.
6x−15−4x=4x+12−4x
2x−15=12
Step 3: Add 15 to both sides.
2x−15+15=12+15
2x=27
Step 4: Divide both sides by 2.
The equation is equivalent to given equation is 2x=27. Therefore, option B is the correct answer.
What is an equivalent equation?Algebraic equations with equivalent solutions or roots are called equivalent equations. An analogous equation is one that is created by adding or removing the identical quantity or expression from both sides of a given equation. An equation is equivalent if both sides are multiplied or divided by the same non-zero value.
The given equation is 3(2x-5)=4(x+3).
Now, 6x-15=4x+12
6x-4x=12+15
2x=27
The equation is equivalent to given equation is 2x=27. Therefore, option B is the correct answer.

Find the diagram attached
Using the similarity theorem
A F/F B = AG/GC
x+1/x+6 = x-1/x+3
Cross multiply
(x-1)(x+6) = (x+1)(x+3)
Expand
x²+6x-x-6 = x²+x+3x+3
5x - 6 = 4x+3
5x-4x = 3+6
x = 9
