Answer:
10x^2-x-24
Step-by-step explanation:
Step-by-step explanation:
First, you have to expand the expression.
[tex](2x + 3)(5x - 8) \\ = (2x)(5x) + (2x)( - 8) + (3)(5x) + (3)( - 8) \\ = 10 {x}^{2} + ( - 16x) + 15x + ( - 24) \\ = 10 {x}^{2} - 16x + 15x - 24 \\ = 10 {x}^{2} - x - 24[/tex]

Find the Area of the Garden (Must show work!!!)
Answer:
162 ft²Step-by-step explanation:
The missing side of the garden is the hypotenuse of a triangle with legs:
(80 - 70) = 10 ft and (40 - 15) = 25 ftThe length of the side is:
[tex]\sqrt{10^2+ 25^2} = \sqrt{725}[/tex] ≈ 27 ftThe area of the garden is:

Which equation represent the nth term of the arithmetic sequence?
Answer:
D. aₙ = 5n - 11Step-by-step explanation:
The equation of the nth term of the arithmetic sequence is: [tex]a_n =a_1+d(n-1)[/tex]
d = 9 - 4 = 5
a₁ = -6
Therefore:
[tex]a_n =-6+5(n-1)\\\\a_n =-6+5n-5\\\\a_n =5n-11[/tex]

Answer:
I) 616
II) 4.53
Step-by-step explanation:
For the first one, just plug in 7 as R.
A = 4 x (22/7) x 7^2
A = 12.57142857 x 49
A = 616
For the second, one, put 452 4/7 as A.
452 4/7 also is 258.285
258.285 = 4 x (22/7) x r^2
258.285 = 12.57142857 x r^2
Divide both sides by 12.57142857
20.55372408 = r^2
Square root 20.55372408 for R.
4.533621519 = R
OR
4.53 = R
A rectangle has an area of 54 square centimeters. The width is 3 more
than 1 times the length. Find the length and width, in centimeters, of the
triangle.
Answer:
W = 6
L = 9
Step-by-step explanation:
area = 54 = L x W
L = W + 3
substitute for L:
54 = W(W + 3)
W² + 3W = 54
W² + 3W - 54 = 0
(W + 9)(W - 6) = 0
W = 6
L = 6 + 3 = 9

a.2,500
b.12,500
c.1,024
d.500
Answer:
A) 2,500
Step-by-step explanation:
Soo.....
A1 = 4
A2 = 4*5 = 20
A3 = 20*5 = 100
A4 = 100*5 = 500
A5 = 500*5 = 2,500

What is the radius of the circle made by Ana's brother in the blue car? Use 3.14 for π and round your answer to the nearest tenth. Show your work.
Answer:
See the explanation
Step-by-step explanation:
Given data
Although we are not given any two vital parameters that are needed to find the radius of a circle
The first is the circumference
And the second is the area
To find the radius with a given circumference we use
C=2πr
To find the radius with a given area we use
A=πr^2
Answer:
220 feet and 126 feet are the circumferences of the two circles
Step-by-step explanation:
Question 7 of 12 Solve: 3x- 8 = 6(1 - 2x) + 16 O A. x = 2 O B. x = 5 O C. x= -2 O D. There are infinitely many solutions.
Answer:
A. x =2
Step-by-step explanation: Rearrange terms 3x - 8 = 6 ( 1 - 2x ) + 16 ---> 3x - 8 = 6 ( -2x + 1 ) +16
Distribute
Add the numbers
Add 8 to both sides of the equation
Simplify
Add 12x to both sides of the equation
Simplify
Divide both sides of the equation by the same term
Simplify -------> x=2

Answer:
1 triangle: 2 m²2 triangles: 4 m²large rectangle: 32 m²small rectangle: 3 m²total area: 39 m²cost of tile: $487.50Step-by-step explanation:
You will run across many examples of poorly edited curriculum materials. This is one of them. We presume that every instance of "inches" should be an instance of "meters". The difference between in and m is not always obvious in a diagram, and m apparently got misinterpreted here.
__
The area of a triangle is given by the formula ...
A = 1/2bh
where b is the base and h is the height perpendicular to the base.
The triangles in this figure have a base of 4 m, and a height of 1 m. Using this formula, we find the area of 1 triangle to be ...
A = 1/2(4 m)(1 m) = 2 square meters . . . . area of 1 triangle
__
The triangles are the same size, so the area of both together is ...
2(2 m²) = 4 square meters . . . . area of both triangles together
__
The large rectangle is 8 m long and 4 m high. Its area is given by the formula ...
A = LW
where the length is L and the width is W. Using this formula, we find the area of the large rectangle to be ...
A = (8 m)(4 m) = 32 m² . . . . area of large rectangle
__
The small rectangle has a length of 3 m and a width of 1 m. Its area is ...
A = (3 m)(1 m) = 3 m² . . . . area of small rectangle
__
The total area is the sum of the areas of the pieces:
total area = 2 triangles + large rectangle + small rectangle
total area = 4 m² + 32 m² + 3 m² = 39 square meters
_____
At $12.50 per square meter, the cost of covering the patio is ...
($12.50/m²)(39 m²) = $487.50 . . . . cost of tile

What is the slope and y-intercept for this line?
Slope
y-intercept
Given:
The table of values.
To find:
The slope and y-intercept for this line.
Solution:
From the given table, we have three (-4,6), (0,3), (4,0).
We need to find the slope and y-intercept for this line.
Consider any two points from the given points.
Consider the line passes through the points (0,3) and (4,0). So, the slope of the line is:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{0-3}{4-0}[/tex]
[tex]m=\dfrac{-3}{4}[/tex]
The line passes through the point (0,3). Here the x-coordinate is 0. So, the y-intercept is 3.
Therefore, the slope of the line is [tex]\dfrac{-3}{4}[/tex] and the y-intercept of the line is 3.
Plz answer the question if u want 30 points.
