The simplification of the polynomial expression will give 3x² - 20x + 8.
How to illustrate the polynomial?The polynomial expression is given as:
(5x² + 13x4) (17x² + 7x - 19) + (5x-7)(3x + 1)
= 5x² + 13x - 4 - 17x² - 7x + 19 + 15x² + 5x - 21x - 7
Then collect like terms
= 5x² + 15x² - 17x² + (13x - 7x + 5x - 21x) - 4 - 7 + 19
= 3x² - 20x + 8.

Isaac is making sandwiches for a group of friends. He needs 3 ounces of meat for each sandwich.
Part A: Isaac is not sure how many sandwiches he will be able to make. Write an expression with a variable that represents the amount of meat Isaac needs for his sandwiches. Identify what the variable represents.
Part B: If Isaac has 18 ounces of meat, how many sandwiches can he make? Create an equation and show all work to solve it.
Answer:
A)
O = 3S
While O is the number of ounces of meat
While S is the number of sandwiches
B)
S= O/3 = 18/3 = 6 Sandwiches
X^2+10x+22=13 1. Rewrite the equation by completing the square your equation should look like (x+c)^2 = d or (x-c)^2=d 2. What was the solution to the equation?
Answer:
(x+5)² = 16
Solution: -1 and -9
Step-by-step explanation:
Given the quadratic equation X^2+10x+22=13
Subtract 22 from both sides
X^2+10x+22-22=13-22
x^2+10x = -9
Complete the square
Add the square of half of coefficient of x to both sides
coefficient of x = 10
half of coefficient of x = 10/2 = 5
square of half of coefficient of x= 5² = 25
Add 25 to both sides
x²+10x + 25 = -9+25
(x+5)² = 16
Hence the required equation is (x+5)² = 16
(x+5)² = 16
square root both sides
√(x+5)² = √16
x+5 = √16
x +5 = ±4
x = +4 - 5 and -4-5
x = -1 and -9
Hence the solution to the equation is -1 and -9

Rose and Carl share a 24-ounce bucket of clay. By the end of the week, Rose has used 3 8 of the bucket, and Carl has used 1 4 of the bucket of clay. How many ounces are left in the bucket?
Answer:Quantity of Clay left = 9ounce
Step-by-step explanation:
Quantity of clay in the bucket = 24 ounce
Quantity of clay used by rose=3/8 of 24 ounce = 4 x 3 = 9 ounce
Quantity of clay used by Carl= 1/4 of 24 ounce = 6 ounce
Therefore Quantity of Clay left = Quantity of clay in the bucket - (Quantity of clay used by rose+ Quantity of clay used by Carl
24 ounce - ( 9ounce + 6 ounce )
24-15ounce
= 9 ounce
What are the restrictions for y for the following equation? X=10/5+y
Answer:
y = -5
Step-by-step explanation:
The restriction for the value of y is the value of the variable that will make the function undefined
The function is undefined when the denominator is zero i.e when 5 + y is zero
5+y = 0
y = 0-5
y = -5
Hence the restrictions is at when y = -5

Rewrite the formula to find the width of the base of the prism if the volume, length of the base, and height of the prism are already known.
Answer:
w = V/lh
Step-by-step explanation:
The volume of a rectangular prism is calculated using the formula V = lwh, where V is the volume of the prism, l and w are the length and width of the base of the prism, respectively, and h is the height of the prism.
Rewrite the formula to find the width of the base of the prism if the volume, length of the base, and height of the prism are already known.
volume of a rectangular prism,V = lwh
Where,
l = length of the base of the prism
w = width of the base of the prism
h = height of the prism
Rewrite the formula to find w
V = lwh
w = V/lh
That is,
width of the base of the prism = volume of the prism divided by length of the base of the prism multiplied by height of the prism

what is the area of this figure?
Answer:
400 in²
Step-by-step explanation:
Consider the figure as a triangle on top of a parallelogram. The tic marks on the sides mean that the lengths with the same tic marks are equal.
The area of the parallelogram is 20×16=320
The area of the triangle is (20×8)/2= 80
Add the two areas: 320 + 80 = 400

In triangle Xyz the measure of angle YXZ is 14.5°, and the measure of angle XYZ is 75°. What is the measure of angle XZY in degrees
Answer:
90.5 degrees
Step-by-step explanation:
The sum of the angle in triangle XYZ is 180 degrees, hence;
m<XYZ + m<YXZ + <XZY = 180
Substitute the given angles
75 + 14.5 + <XZY = 180
89.5+m<XZY = 180
m<XZY = 180 - 89.5
m<XZY = 90.5 degrees
Hence the measure of angle XZY in degrees is 90.5 degrees

A farmer need five men to clear his farm in 10 days how men will he need, if must finish clearing in 2 days if they work at the same rate
Answer:
1 person
Step-by-step explanation:
It is given that a farmer wants 5 persons to complete a work of clearing his field in ten number of days.
We have to find out the number of persons required if the farmer needs to clear his field in 2 number of days.
Therefore according to the information given :
10 days = 5 persons
∴ 1 day = [tex]$\frac{5}{10}$[/tex] persons
So 2 days = [tex]$\frac{5}{10}\times 2$[/tex] persons
[tex]$=\frac{5}{5}$[/tex] person
= 1 person
