Answer:
-2x - 8
Step-by-step explanation:
Perimeter = 2*(length + width)
= 2* (-3x + 1 + 2x - 5)
= 2* (-3x + 2x + 1 - 5)
Combine like terms. (-3x and 2x are like terms ; 1 and (-5) are like terms
= 2* (-x -4)
Use distributive property: a*(b+c) = a*b +a*c
= 2*(-x) - 4 *2
= -2x - 8

what is the volume of the rectangular prism
It is all the numbers multiplied together. 135
Answer:
[tex]\Huge\boxed{D.135 cm^3}[/tex]
Step-by-step explanation:
Hello There!
We can find the volume of the figure by using the formula for volume of a rectangular prism
[tex]V=lwh[/tex]
where l = length, w = width and h = height
we are given all of the dimensions so all we have to do is plug in the values
so
V = 3 x 9 x 5
3x9=27
27x5=135
so the volume of the rectangular prism is 135 cm³

Leah's rectangular driveway is 48 feet long and 14 feet wide. With sidewalk chalk, Leah drew a straight diagonal line on her driveway from one corner to the opposite corner.
How long is the diagonal line Leah drew?
25 feet

50 feet
62 feet
[tex]48^2+14^2=x^2\\x^2=2500\\x=50[/tex]
The length of the diagonal drawn by Leah will be 50 feets
Given the Parameters :
Length = 48 feet Width = 14 feetsThe length of the diagonal is the value of the hypotenus in a right angles triangle :
Let the length of the diagonal = d
d = √(length)² + (width)²
d = √48² + 16²
d = √2304 + 256
d = √2560
d = 50.5961 feets
Therefore, the closest value for the length of the diagonal in the options given is 50 feets

Answer:
9,775,069,161
Step-by-step explanation:
The field has the shape of a trapezoid. Its area can be found using the formula for the area of a trapezoid:
A = (1/2)(b1 +b2)h
A = (1/2)(399 +594)(506) = 251,229 . . . . . . acres
__
At 38909 plants per acre, the number of plants that should be planted for maximum yield is ...
(251,229 ac)(38,909 plants/ac) = 9,775,069,161 plants
_____
Comment on units
The problem statement tells us "each unit of coordinate plane represents one acre." An acre is a unit of area, so we have to assume this means that each square unit represents one acre. That means each unit on each axis is about 208.71 feet, the dimension that would have to be squared to get an area of one acre--43,560 square feet.
How do I factor the polynomial -7y+y^2-30? I can do it in standard form but now im confused. Please help.
Answer:
your answer would be
(y - 10) (y + 3)
hope this helps
Answer:
Step-by-step explanation:
-7y+y^2-30 is presented legally, but not logically I will re-write it better
just re-write in standard form
y^2 - 7y - 30
y² - 7y - 30 is it better now?
(y - 10) (y + 3)

What is fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given:
It takes an old printer 8 hours to print all the pictures for the yearbook.
A modern printer can do the same job in 5 hours.
If both work together,
it will take,
x(1/8 + 1/5) = 1
x(8 + 5)/40 = 1
8x + 5x = 40
x = 40/13
x = 3.07
x = approximately 3.1 hours.
Therefore, the work will be done in 40/13 hours.

The sides of a polygon are 3cm, 5cm, 6cm, 8cm and 10cm. The perimeter of a second similar polygon is 48cm. What is the length of the longest side of the second polygon?
Answer:
Length of the longest side of the similar polygon = 15 cm
Step-by-step explanation:
Sides of a polygon are 3 cm, 5 cm, 6 cm, 8 cm and 10 cm
Perimeter of the polygon = 3 + 5 + 6 + 8 + 10
= 32 cm
Perimeter of the similar polygon = 48 cm
Since, scale factor = [tex]\frac{\text{Perimeter of the similar polygon}}{\text{Perimeter of the original polygon}}[/tex]
= [tex]\frac{48}{32}[/tex]
= 1.5
Since, scale factor = [tex]\frac{\text{Dimension of the similar polygon}}{\text{Dimension of the original polygon}}[/tex]
1.5 = [tex]\frac{\text{Dimension of the similar polygon}}{10}[/tex]
Dimension of the similar polygon = 1.5 × 10
= 15 cm
Therefore, longest side of the similar polygon = 15 cm
