Answer:
A = 10W - W²
Step-by-step explanation:
Perimeter of a rectangle = 2(L+W)
Area of a rectangle =LW
L is the length
W is the width
Given
Perimeter = 20m
20 = 2 (L+W)
10 = L+W
L = 10 - W ....2
Substitute equation 2 into the formula for calculating the area
Recall that A = LW
A = (10-W)W
A = 10W - W²
Hence the area of the rectangle as a function of the length of ones its side is expressed as A = 10W - W²

b.write the input and output values as ordered pairs (hint: there are four order pairs.)
c. How did the order pairs change ?
A. 8, 14, 20, 26
B. (1, 8), (3, 14), (5, 20), (7, 26)
C. As x increased by 2, g(x) increased by 6. If x increases by 1, g(x) will increase by 3.

a library has 8,000 books and is adding 500 more each year. does the word problem represent a linear or exponential equation??
Answer:
This problem represents a linear equation.
Step-by-step explanation:
A linear equation is by adding to a certain number, but an exponential equation is multiplying by a certain number. Therefore, it is a linear equation.
Find the measure of line segment EF. Please!!
Answer:
EF = 26
Step-by-step explanation:
From the question, we have that arc EF and arc CD are equal
what this indicates is that the line that bounds these arcs too will be equal
Hence, CD equals EF
Thus;
9x-1 = 41-5x
9x + 5x = 41 + 1
14x = 42
x = 42/14
x = 3
Recall;
EF is 41-5x
EF = 41-5(3)
EF = 41-15
EF = 26

Answer:
Let's simplify step-by-step.
− x + 3 − ( x − 5 )
Distribute the Negative Sign:
= − x + 3 + − 1 ( x − 5 )
= − x + 3 + − 1x + ( − 1 ) ( − 5 )
= − x + 3 + − x + 5
Combine Like Terms:
= − x + 3 + − x + 5
= ( − x + − x ) + ( 3 + 5 )
= − 2x + 8
Answer:
= − 2x + 8

Consider the following prisms, whose bases are both squares.
Naomi tried to use Cavalieri's principle to show that the two figures have the same volume.
"The base areas are the same. Therefore, corresponding cross-sections have the same area. So the volumes must be the same."
What is the first mistake Naomi made?
Answer: C: she did not establish that heights are the same
Naomi mistaken about the bases.
What is difference between square and a rhombus?A square and a rhombus both have sides equal in length. But square has all its angles equal to 90 degrees, but a rhombus only has its opposite angles equal.
Every rhombus is not a square, The reason is that rhombus does not contain any right angles, so it would not a square.
Given two parallel piped figures
Naomi is mistaken by the base area as the bases are one is a a square and other one is a rhombus.
Hence, Naomi mistaken about the bases.

Could someone help here, thankyou!
Answer:
x = 6 cm
Step-by-step explanation:
Given ratio of sides of similar figures = a : b , then
ratio of areas = a² : b²
Here ratio of areas = 5 : 45 = 1 : 9 , so
ratio of sides = [tex]\sqrt{1}[/tex] : [tex]\sqrt{9}[/tex] = 1 : 3
Thus side of B is 3 times side of A

Find the value of x.
Answer:
x=77°
Step-by-step explanation:
All quadrilaterals' interior angles sum to 360°, so to solve one angle in the trapezoid, we can subtract the angles we have from 360.
So x=360-(60+128+95)=77°
x=77°

Lines CD and DE are tangent to circle A shown below: Lines CD and DE are tangent to circle A and intersect at point D. Arc CE measures 112 degrees. Point B lies on circle A. If Arc CE is 112°, what is the measure of ∠CDE? (4 points) Question 5 options: 1) 124° 2) 136° 3) 68° 4) 56°
Answer:
Option (3)
Step-by-step explanation:
By the theorem, angle between two tangents intersecting each other outside the circle is half of the difference between intercepted arcs.
From the figure attached,
Two tangents CD and DE are intersecting each other at point D outside the circle A.
Two intercepted arcs are minor arc CE and major arc CBE,
Measure of arc CE = 112°
Therefore, measure of major arc CBE = 360° - 112°
= 248°
m(∠CDE) = [tex]\frac{1}{2}(\text{arcCBE}-\text{arcCE})[/tex]
= [tex]\frac{1}{2}(248-112)[/tex]
= [tex]\frac{1}{2}\times 136[/tex]
= 68°
Option (3) will be the correct option.

C
