The area of a rectangular garden is represented by the polynomial shown below.
x2 + 19x - 42
What are the dimensions (length and width) of the rectangular garden? ***Hint: Factor (x method). ***
a(x + 21) and (x - 2)
b(x - 21) and (x + 2)
c(x + 42) and (x - 1)
d(x-6) and (x + 7)
Is b) Step-by-step explanation:
The length and the width of the rectangular garden will be ( x + 21) and x - 2 respectively.
What is a quadratic equation?Quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Given that the area of a rectangular garden is represented by the polynomial is shown x² + 19x - 42. The length and the width will be calculated by factorizing the given quadratic equation.
x² + 19x - 42 = 0
x² -21x + 2x - 42 = 0
x ( x - 21 ) + 2 ( x - 21 ) = 0
( x + 2 ) ( x - 21 ) = 0
Therefore, the length and the width of the rectangular garden will be ( x + 21) and x - 2 respectively.

Paula used 134 cups of flour for a recipe. How many cups y of flour did Paula have if she had x cups before making the recipe? Write an equation to represent the situation.
Answer:
y = x - 1 3/4*
Step-by-step explanation:
If 1 3/4 is used, then subtracting that from the previous amount will give you the amount that Paula has currently
* My answer is only correct if you meant 1 3/4, not 134. If you meant 134, then the answer would be y = x - 134

During a read-a-thon John reads for 125 minutes and Dakota reads for 89 minutes. Their friend Will plans to read for more minutes than both of them combined. Which inequality represents w, the number of minutes that Will should read for? Choose all that are correct.
Answer: The required inequality: w> 214
Step-by-step explanation:
Given: Tike taken by John = 125 minutes
Time taken by Dakota = 89 minutes
Combined time = 125 +89 minutes
= 214 minutes
Time taken by Will > Combined time taken by John and Dakota
Let w be the number of minutes that Will should read for.
The required inequality: w> 214

What is the slope of y = -5 + 42?
Answer:
slope should be -5
Step-by-step explanation:
the equation is y=-5+42
slope equation form is y=mx+b
m is the slope in the equation, b is the y-intercept(where it hits the line if graphed)
so b should be 42 and slope should be -5

Kathy wants to paint the faces of her standard six-sided die so that each face is either red or blue. However, she does not want all of the faces to be the same color. How many ways are there for Kathy to paint her die?
Answer:
The number of ways Kathy can paint her die is 52 ways
Step-by-step explanation:
The permutation and combination related question is answered as follows;
The number of faces in the six-sided die = 6
The number of colors available for painting the six-sided die = 2 colors
Therefore, we have, the total number of ways Kathy can paint her die, 'n', given as follows;
n = ₆P₂ + 2₄P₄ + 2₄P₃ + ₄P₂
Where;
₆P₂ = The number of ways of arranging 2 objects in 6 spaces = 30
₄P₄ = The number of ways of arranging 4 objects in 4 spaces = 1
₄P₃ = The number of ways of arranging 3 objects in 4 spaces = 4
₄P₂ = The number of ways of arranging 2 objects in 4 spaces = 12
∴ n = 30 + 2×1 + 2×4 + 12 = 52
The number of ways Kathy can paint her die, n = 52 ways.
