The area of the shape that is the combination of rectangle and trapezoid will be 71 square inches.
What is the area?The quantity area demonstrates the amount of a sector on a planar or hemispherical cup. Surface area refers to the area of an open surface or the border of a multi-object, whereas the area of a plane region or plane field refers to the area of a form or planar material.
The shape is a combination of a rectangle and a trapezoid.
The area is the summation of the area of the rectangle and the area of the trapezoid. Then we have
Area = Area of the rectangle + Area of the trapezoid
Area = 5 x 9 + (1/2) x (4 + 9) x 4
Area = 45 + 26
Area = 71 square inches
The area of the shape that is the combination of rectangle and trapezoid will be 71 square inches.

4)[tex]2x^2-6x-36=0[/tex]
5)[tex]x^2-5x-84=0[/tex]
Step-by-step explanation:
1) The length of a wooden frame is 1 foot longer than its width and its area is equal to 12 sq. ft.
Let the width be x
We are given that length of a wooden frame is 1 foot longer than its width
So, Length = x+1
Area of rectangular frame =[tex]Length \times Breadth = x(x+1)[/tex]
ATQ
x(x+1)=12
[tex]x^2+x-12=0[/tex]
2)The length of the floor is 8 m longer than its width and there is 20 square meters.
Let the width be x
We are given that length of the floor is 8 m longer than its width
So, Length = x+8
Area of floor= [tex]Length \times Breadth = x(x+8)[/tex]
ATQ
x(x+8)=20
[tex]x^2+8x-20=0[/tex]
3)The length of a plywood is 0.9 m more than its width and its area is 0.36 m2.
Let the width be x
We are given that length of a plywood is 0.9 m more than its width
So, Length = x+0.9
Area of plywood=[tex]Length \times Breadth = x(x+0.9)[/tex]
ATQ
x(x+0.9)=0.36
[tex]x^2+0.9x-0.36=0[/tex]
4)The area of rectangle whose length is six less than twice its width is thirty-six
Let the width be x
We are given that length is six less than twice its width
So, Length = 2x-6
Area of rectangle = Length \times Breadth = x(2x-6)
ATQ
x(2x-6)=36
[tex]2x^2-6x-36=0[/tex]
5)The width of a rectangular plot is 5 m less than its length and its area is 84 m2.
Let the length be x
Width = x-5
Area =[tex]Length \times Breadth = x(x-5)[/tex]
ATQ
x(x-5)=84
[tex]x^2-5x-84=0[/tex]

Tabby is building two models of the Eiffel Tower. The scale factor of Model 2 to Model 1 is 1/4
____________Eiffel Tower(ft) _ M 1 (in) _M2 (in)
Height _______ 984 ______11.808 ____?
W of base ____ 328 _______? _______?
Answer:
Model 1 :
Width of Base = 328 * 0.012 = 3.936 inch
Model 2 :
Height = 11.808 * 4 = 47.232 inches
Width of base = 4 * 3.936 = 15.744 inches
Step-by-step explanation:
____________Eiffel Tower(ft) _ M 1 (in) _M2 (in)
Height _______ 984 ______11.808 ____?
W of base ____ 328 _______? _______?
Scale factor of Model 2 to Model 1 is 1/4
Model 1 : Model 2
1 : 4
The scale factor of actual tower to model 1
984ft = 11.808 inches
Hence,
1 ft = 11.808 / 984
1 ft = 0.012 inch
Model 1 :
Width of Base = 328 * 0.012 = 3.936 inch
Since ;
Model 1 : Model 2 ; 1 / 4
1 : 4
Model 2 :
Height = 11.808 * 4 = 47.232 inches
Width of base = 4 * 3.936 = 15.744 inches

Can someone help me find the scale factor and the missing sides please?
Answer:
x = 6, y = 45
Step-by-step explanation:
[tex]scale \: factor = \frac{13}{32.5} \\ = \frac{2}{5} \\ \\ \frac{x}{15} = \frac{18}{y} = \frac{2}{5} \\ \\ \implies \frac{x}{15} = \frac{2}{5} \\ \\ x = \frac{2 \times 15}{5} \\ \\ x = 6 \\ \\ \frac{18}{y} = \frac{2}{5} \\ \\ y = \frac{5 \times 18}{2} \\ \\ y = 45[/tex]

Tameca already has $55 dollars in her savings account. If she puts $5 per week in her account, write and solve an inequality to find out how many weeks she must save to have at least $100 in her account.
Answer:
9 weeks
Step-by-step explanation:
5 x 9 = 45
45 + 55 = 100
Answer:
55 + 5x ≥ 100.
5x ≥ 45.
Step-by-step explanation:
write the first equation shown above first, then subtract 55 from 55 and 55 from 100. do not use 0 later on in your equation! 100 - 55 = 45. then write the second equation. after you write the second equation, divide 5 by 5 and 45 by 5. do not use 0 later on in your equation! 45 divided by 5 = 9. she must save for 9 weeks. i hope this works! here is a picture of my work to help you understand it better! <3 it’s kind of blurry, but if you focus enough it’s easier to read.

You are a contractor and charge $65 for a site visit plus an additional $15 per hour for each hour you spend working at the site. Write and solve an equation to determine how many total hours you have to work to earn $950 working at two separate work sites.
Answer:
54.6 hours
Step-by-step explanation:
65x2 is 130 130-950 is 820 then 820 divided by 15 is 54.6 therefore meaning you have to work 54.6 hours to get 950$ you can check this by doing 54.6x15+130, might not be exact because i rounded to the nearest tenth.

What is Straight Line?A straight line is an infinite length line that does not have any curves on it. A straight line can be formed between two points also but both the ends extend to infinity.
Here, we know that slope intercept form of straight line;
y = mx + c
Given equation;
y = -3x - 2
compare this equation with general equation, we get
m = -3 and c = -2
Thus, The slope of given line is -3 and the y-intercept of the line is -2.
