Answer:
a) Area = 2x² + 3x - 2
b) Perimeter = 64x + 28
c) Length = 60 feet and Width = 50 feet
Step-by-step explanation:
It is given that:
Length of building = 12x + 24
Width of building = 20x - 10
Area = Length * Width
Area = (12x + 24) * (20x - 10)
Area = 12x(20x - 10) +24(20x-10)
Area = [tex]240x^2-120x+480x-240[/tex]
Area = [tex]240x^2+360x-240 = 2x^2+3x-2[/tex]
Perimeter = 2 (Length + Width )
Perimeter = 2 (12x + 24 + 20x - 10 ) = 2 (32x +14 )
Perimeter = 64x + 28
Putting Perimeter = 220
220 = 64x + 28
64x = 220 - 28
64x = 192
Dividing both sides by 64
x = 3
Length = 12(3) + 24 = 36 + 24 = 60 feet
Width = 20(3) - 10 = 60 - 10 = 50 feet
Therefore,
a) Area = 2x² + 3x - 2
b) Perimeter = 64x + 28
c) Length = 60 feet and Width = 50 feet

Answer: y=-(5/4)x+5
Step-by-step explanation:
The parent function of a linear line is y=mx+b where m is the slope and b is the y intercept so:
Y=-(5/4)x+5
I seriously hate my fat finger xd help
Answer:
They are equal to one another
Step-by-step explanation:
1/2 is equal to .5, so id you have 6.5 on one side and 6.5 on the other, they are equal.
Answer: =
6 [tex]\frac{1}{2}[/tex] = 50/100
=6.5
so 6.5 = 6 [tex]\frac{1}{2}[/tex]
a) Solve 3(x – 5) = 18
Answer:
x = 11
Step-by-step explanation:
3(x-5) = 18
Step one: Distrubute 3 to the numbers in the parenthesis.
3x - 15 = 18
Step two: Add 15 on both sides
3x = 33
Step three: Divide by 3 on both sides
x = 11

I need help I’m slow
Answer:
Between 25 and -18 is 0.
Between -18 and -12 (in the corner) is again, 0.
Between -12 and -18 (left side corner, bottom) is 5.
Between 0 and -12 (top left corner) is -18.
Between 0 and 5 (top of page) is 25
Between 5 and -12 (bottom right corner) is 0
Between -18 and 25 (middle) is 5
Between -18 and 0 (middle) is -12
Between -12 and 0 (middle-left) is 5
Between -12 and -18 (not corner, but above it) is 25.

KEVI is an isosceles trapezoid.
If KN 10, NV = x, and IE = 2x+6,
what is the length of KV?
Answer:
14
Step-by-step explanation:
A trapezoid is a quadrilateral (has four sides and four angles) with a pair of opposite parallel sides. The pair of opposite parallel side is known as the base.
An isosceles trapezoid is a trapezoid with equal legs. The diagonals are also equal and both the upper and lower base angles are congruent.
From the question:
KV = IE = 2x + 6 (diagonals of a trapezoid are congruent)
From line segment addition postulate:
KV = KN + NV
substituting:
2x + 6 = 10 + x
2x + 6 - x = 10
x + 6 = 10
x = 10 - 6
x = 4
KV = 2x + 6
substituting x = 4:
KV = 2(4) + 6
KV = 14
McKenna earns $12 per hour mowing her grandmother yard.
Answer:
???
Step-by-step explanation:
How can you use the properties of equality to write equivalent equations?
If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable.
a = b and c ≠0, then a c = a c . Another example Consider the equation 12 = 12. Divide both sides by 4.
A person Rents a canoe for 4 Hours and paid a total of $36. of Renting a canoe costs am initial fee of the $2 Plus an additional amount for each hour the canoe is rented,which graph represents the total cost,y, in dollars of renting a canoe for x hours
Answer:
Additional fee or hour = $8.5
y = $2 + 8.5x
Step-by-step explanation:
Given that :
Total paid = $36
Number of hours = 4
Initial rental fee = $2
Additional fee per hour = a
Total amount = initial rental fee + additional fee per hour * number of hours
36 = 2 + 4a
36 - 2 = 4a
34 = 4a
a = 8.5
Hourly fee = $8.5
Therefore, the cost formula
y = initial fee + regular fee * number of hours
y = $2 + 8.5x

Step-by-step explanation:
Hope you find this helpful!
Answer: It does because 1/3 is equal to 2/6. in order to add them, they have to have the same denominator. and if you add 2/6 to 1/6, you get 3/6. 3/6 is also equal to 1/2, if you divide both sides by 3.

Answer:
90
Step-by-step explanation:
a triangle's angles all add up to 180. take 51 and 39 away from 180 and you get 90
Answer: 90 degrees
Step-by-step explanation:
Theorem:
a+b+c=180 degrees
39 degrees + 51 degrees + x degrees = 180 degrees
39 + 51 = 90
180 - 90 = 90

Answer:
the equation that has the same solution as the given expression is
m + 7.28 = 18.28
Step-by-step explanation:
Given expression;
0.2m = 2.20
To solve for m, divide both sides by 0.2
[tex]\frac{0.2 m}{0.2} = \frac{2.2}{0.2} \\\\m = 11[/tex]
From the given options, the equation that has the same solution as the given expression is m + 7.28 = 18.28
Solve the equation to confirm as follows;
m + 7.28 = 18.28
collect like terms
m = 18.28 - 7.28
m = 11

X+36 is less than 40 write equation
Answer:
x<4
Step-by-step explanation:
x+36 is less than 40
x+36<40
Subtract 36 from both sides
x<4This equation means, that in order for the equation to be true, x must be less than 4.
Answer:
x<4
Step-by-step explanation:
x+36=40
you do 36- 40 and get 4 then it would be x<4
