What is the greatest common factor of 42 and 64
Please help! What is |x-3|=9
Answer:
x = 12 or x = -6
Step-by-step explanation:
Solve for x over the integers:
abs(x - 3) = 9
Split the equation into two possible cases:
x - 3 = 9 or x - 3 = -9
Add 3 to both sides:
x = 12 or x - 3 = -9
Add 3 to both sides:
Answer: x = 12 or x = -6
Solve each equation. Be sure to check for extraneous solutions 53=5|p-4|+8
Simplify the following expression:

Answer:
2nd option
Step-by-step explanation:
Given
2x - 8y + 3x² + 7y - 12x ← collect like terms
= 3x² + (2x - 12x) + (- 8y + 7y)
= 3x² + (- 10x) + (- y)
= 3x² - 10x - y

I need help with the perimeter
the measurements of a rectangular tablecloth are 94 cm and 64 cm.
how many cm does the perimeter of the tablecloth measure?
how many cm of fabric were used to make it?
Step-by-step explanation:
1) Perimeter = 2(l + w)
Perimeter = 2(94 + 64)
Perimeter= 2(158) = 361 cm
2) Fabric required = Area
Area = l × b
Area = 94 × 64
Area = 6016 cm²
The measurements of a rectangular tablecloth are 94 cm and 64 cm.
Solution and Answer:How many cm does the perimeter of the tablecloth measure?
Perimeter = 2(Length × Width)P = 2(l + w)P = 2(94 + 64)P = 2(158)P = 316 cmTherefore, the perimeter of the tablecloth is 316 cm.
How many cm of fabric were used to make it?
Area = length × widthA = l × wA = 94cm × 64 cmA = 6,016 cm²Therefore, the fabric is 6,016 cm².

What is the area of the square?
24 mm
288 square millimeters
96 square millimeters
312 pi square millimeters
576 square millimeters
Answer:
576 mm²

Answer:
x=6
Step-by-step explanation:
Answer:
Step-by-step explanation:
This is one of those things that will drive you insane until you understand the answer.
Every y value is 4 no matter what x is.
The perpendicular will meet y = 4 at the point (6,4)
Answer: So the equation has to be x = 6.
The blue line is y = 4
The red line is x = 6

Hanks pickup can travel 45 miles on 3 gallons of gas. How many gallons will Hanks pickup need to travel 30 miles?
We have an algebra problem.
We will find that Hank's pickup needs 2 gallons of gas to travel 30 miles.
The information given is:
The pickup can travel 45 miles on 3 gallons of gas.
To find the number of miles that the pickup can travel per gallon of gas, we need to find the quotient between the amount that he travels (45 miles) and the amount of gas that he uses (3 gallons)
This is:
r = (45 miles)/(3 gallons) = 15 miles/gallon.
Now that we know this, the number of gallons needed to travel 30 miles is given by:
N = (30 miles)/(15 miles/gallon) = 2 gallons.
N = 2 gallons.
The pickup needs 2 gallons to travel 30 miles.

please helppppppppppp
Answer:
see explanation
Step-by-step explanation:
Substitute the given values of x into f : x → [tex]\frac{3}{7}[/tex] x + 4
x = - 14 → ([tex]\frac{3}{7}[/tex] × - 14) + 4 = (3 × - 2) + 4 = - 6 + 4 = - 2
x = 28 → ( [tex]\frac{3}{7}[/tex] × 28) + 4 = (3 × 4) + 4 = 12 + 4 = 16
x = [tex]\frac{7}{8}[/tex] → ([tex]\frac{3}{7}[/tex] × [tex]\frac{7}{8}[/tex] ) + 4 = [tex]\frac{3}{8}[/tex] + 4 = [tex]\frac{3}{8}[/tex] + [tex]\frac{32}{8}[/tex] = [tex]\frac{35}{8}[/tex]
x = - [tex]\frac{2}{9}[/tex] → ([tex]\frac{3}{7}[/tex] × - [tex]\frac{2}{9}[/tex] ) + 4 = ([tex]\frac{1}{7}[/tex] × - [tex]\frac{2}{3}[/tex]) + 4 = - [tex]\frac{2}{21}[/tex] + [tex]\frac{84}{21}[/tex] = [tex]\frac{82}{21}[/tex]
Answer:
See below in bold.
Step-by-step explanation:
1. 3/7 * -14 + 4
= -6 + 4
= -2.
2. 3/7 * 28 + 4
= 12 + 4
= 16.
3 3/7 * 7/8 + 4
= 3/8 + 4
= 35/8 or 4 3/8.
4. 3/7 * -2/9 + 4
= -6/63 + 4
= -2/21 + 4
= -82/21 or -3 19/21.
Answer part A and part B
Answer: Part A: a square pyramid Part B: 84 square feet
Step-by-step explanation:
Part A: The shape will have a base that is a square with triangles on each of its edges that connect at a point at the top.
Part B: The amount of nylon needed is the surface area of the net. There is a square and two triangles. The square has a side length of 6 so its area will be 6*6=36 square feet. Each triangle has a base of 6 and a height of 4 so each of their areas will be [tex]\frac{6*4}{2}=12[/tex] square feet. Adding up the area of the 4 triangles and the square gives us 4*12+36=84 square feet.
