Answer:
20
Step-by-step explanation:
Given :
Length = l
Width = w
Area of square = 45
Let side of square = x
Area of square = x²
45 = x²
√45 = x
l of rectangle = x + 5 = √45 + 5
w of rectangle = x -5 = √45 -5
Area of rectangle= l * w
Area = (√45 + 5) * (√45 - 5)
Area = 45 - 5√45 + 5√45 -25
Area = 45 -25
Area of rectangle = 20

Find the value of x in each diagram
Answer:
A. x = 8.
B. x = 31.
C. x = 32.
Step-by-step explanation:
Here. the sum of the 2 parallel sides of the trapezoid = 2 * length of the middle line segment.
MN + RS = 2PQ
32+ x = 2*20
x = 40 - 32
x = 8.
MN + RS = 2PQ
20 + 42 = 2PQ
2x = 62
x = 31
MN + RS = 2PQ
22 + 42 = 2PQ
2x = 64
x = 32.

Solve for b
-11b+7 = 40
Answer:
b=-3
Step-by-step explanation:
-11b+7=40
-7 -7
-11b=40-7
-11b=33
-11b/-11=33/-11
b=-3
CHECK:
-11b+7 = 40
Substitute -3 for b:
-11(-3)+7=40
Solve:
33+7=40
40=40
Therefore b does in fact equal -3.
I hope this helped you.

85 points! Sketch the following image on a blank piece of paper and rotate triangle ABC 80 degrees. 1st pic attached: is the triangle and 2nd pic attached is what I drew.... did i do it right?
Answer:
Step-by-step explanation:
It can never be perfect, but what I see, I think yes, because u didn't rotate it 90 degrees since it's not a right triangle, but u did rotate it where it looks close to 90 degrees, so it does look like its 80 degrees as a rotation. Question, does it not say how to rotate it? Like 80 degrees clockwise, or 80 degrees counterclockwise?

Describe the lines below as parallel,
perpendicular, or neither.
2x - 5y = 25 and y= 5x+3
Answer:
Neither.
Step-by-step explanation:
First, we write 2x - 5y = 25 in slope-intercept form. That gets us y = 2/5x - 5. Now, we graph both the lines (check the image attached). Parallel means extending in the same direction, everywhere equidistant. Perpendicular means the relationship between two lines that meet at a right angle (90 degrees). As we can see in the screenshot, these lines don't fit any of these categories, so we put "neither."
The lines 2x - 5y = 25 and y = 5x + 3 are neither parallel nor perpendicular
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Equations of two lines are given, They are 2x - 5y = 25 and y = 5x + 3.
Now, Writing them in slope-intercept form,
2x - 5y = 25.
- 5y = - 2x + 25.
y = (2/5)x - 5.
And,
y = 5x + 3.
Now, We know lines parallel to each other have the same slope, and lines perpendicular to each other have a slope that is negative reciprocal of each other.
Therefore the lines y = (2/5)x - 5 and y = 5x + 3 are neither parallel nor perpendicular.

A carpenter is making a wooden window frame that has a width of 1 inch. How much wood does the carpenter need to build the frame? 5.5 + 106 square inches 5.5 + 116 square inches 5.5 + 153 square inches 5.5 + 162 square inches
Diagram attached
Answer:
5.5+106 square inches
Step-by-step explanation:
The wooden frame has different shapes- semi circle, rectangles and we would have to calculate area of all the shapes to get the wood required.
To get area of the circle, we use the formula π(R²-r²)/2. Subtract the inner radius from the outer radius =
π(6²-5²)/2= 11π/2
=5.5π square inches
We add area of the semi circle to area of the 3 rectangles from the diagram:
2×1×48×10×1=106 square inches
The rectangle with 10 inches is because we subtracted one inch from both sides of the 12 inches rectangle to avoid repetition and overvaluing the area
Total area =5.5π +106 square inches
Options must have ommitted the "π"
Answer:
5.5 + 106 square inches

PLEAS HELP ASAP!!! What is the equation for the line in slope-intercept form?
Answer:
[tex]y = 8x[/tex]
Step-by-step explanation:
Find slope by using Rise/Run.
Use two coordinate points that are part of the graph.
(0,0) and (2,16)
[tex]m = \frac{16 - 0}{2 - 0} \\ m = \frac{16}{2} \\ m = 8[/tex]
We have the slope. We need to find the y-intercept.
From the graph, the graph passes y-axis (0,0). Therefore the y-intercept is at (0,0)
[tex]y = mx + b[/tex]
[tex]m = 8 \\ b = 0[/tex]
Substitute m = 8 and b = 0 in the equation.
[tex]y = 8x + 0 \\ y = 8x[/tex]
