Find the perimeter of the figure if the following is true:
A= x^2
B= 4x + 8
C= 2x^2
D= x
Answers
The perimeter of a figure is the distance around the outside of the figure. To find the perimeter of this figure, we need to add the lengths of all sides. This is:
P = A + B + C + D
P = x² + 4x + 8 + 2x² + x
P = 3x² + 5x + 8
The perimeter is 3x² + 5x + 8.
= x^2 + 4x + 8 + 2x^2 + x
= 3x^2 + 5x + 8
.:. The perimeter is 3x^2 + 5x + 8
- The perimeter is the sum of all angles.

Explain how to determine whether a product(answer to a multiplication problem) will be positive or negative. Write in complete sentences
Answers
Answer:
when the signs of the two numbers being multiplied are the same, the product answer would be positive.And when the signs of the two numbers being multiplied are different, the product answer would be negative.Step-by-step explanation:
Whether a prdocut will be positive or negative really depends on the signs of the two numbers being multiplied.
In other words,
when the signs of the two numbers being multiplied are the same, the product answer would be positive.(positive number) × (positive number) = positive number
(negative number) × (negative number) = positive number
For example, when we multiply the positive numbers 3 and 4, the product will be positive.
i.e. 3 × 4 = 12
Also, when we multiply the negative numbers 3 and 4, the product will again be positive.
i.e. (-3) × (-4) = 12
And when the signs of the two numbers being multiplied are different, the product answer would be negative.(positive number) × (negative number) = negative number
For example, when we multiply the positive number 3 and negative number -4, the product will be negative.
i.e. (3) × (-4) = -12

Find the intercepts of the function 2x - y = 6.
Answers
So the given function is in standard form: Ax + By = C
To find the x-intercept set 'y' to 0 and vice-versa
Solve for x:
2x - 0 = 6
+0 +0
2x = 6
/2 /2
x = 3
x-int: (3, 0)
Solve for y:
2(0) - y = 6
0 - y = 6
-0 -0
-y = 6
/-1 /-1
y = -6

Shipping Company A charges $14 plus $2.25 a pound to ship overnight packages. Shipping Company B charges $20 plus $1.50 a pound to
ship an overnight package. For what weight is the charge the same for the two companies?
Let p represent the number of pounds. Select the correct values to write an equation to represent the situation
Answers
Answer:
8 pounds
Step-by-step explanation:
Shipping Company A = 14 + 2.25p
Shipping Company B = 20 + 1.50p
Where,
p = the number of pounds.
For what weight is the charge the same for the two companies
Equate the charges of the two companies
14 + 2.25p = 20 + 1.50p
14 - 20 = 1.50p - 2.25p
-6 = -0.75p
Divide both sides by -0.75
p = -6 / -0.75
= 8
p = 8 pounds

2x+y=4; x−y=2
Step: Solve 2x+y = 4 for y:
2x + y + −2x = 4 + −2x (Add -2x to both sides)
y = −2x+4
Step: Substitute −2x+4 for y in x−y=2:
x − y=2
x−(−2x + 4)=2
3x − 4=2(Simplify both sides of the equation)
3x − 4 + 4 = 2+4 (Add 4 to both sides)
3x =6
(Divide both sides by 3)
x=2
Step: Substitute2forxiny=−2x+4:
y= −2x + 4
y=(−2)(2) + 4
y=0 (Simplify both sides of the equation)

Answers
Answer:
88%
Step-by-step explanation:
From the question given above, the following data were obtained:
Original amount = $ 90
Discounted amount = $ 79.20
Percentage of discount =?
Let the percentage of discount be y %
Thus, we can obtain the value of y as follow:
y /100 × 90 = 79.20
90y /100 = 79.20
Cross multiply
90y = 100 × 79.20
90y = 7920
Divide both side by 90
y = 7920/90
y = 88
Thus, the percentage discount of the blender is 88%
