Part (a) :
Formula : Perimeter = 2 (Length + Width)⇒ 278 = 2(54 + Length)⇒ 139 = 54 + LengthLength = 139 - 54 = 85 mPart (b) :
Formula : Area = Length × Width⇒ 8811 = 99 x Width⇒ Width = 8811/99Width = 89 cmAnswer:
(a) The length is 85 m.
(b) The width is 89 cm.
Step-by-step explanation:
(a)
Perimeter (P) formula using the length (L) and width (W) of a rectangle.
P = 2L + 2W
P = 278 m
W = 54 m
278 = 2L + 2(54)
2L + 108 = 278
2L = 170
L = 85
Answer: The length is 85 m.
(b)
Area (A) formula using the length (L) and width (W) of a rectangle.
A = LW
A = 8811 cm²
L = 99 cm
8811 = 99 × W
W = 8811/99
W = 89
Answer: The width is 89 cm.

Find the new dimensions of the figure given at right when it is enlarged by scale factor of 2.5 then find the perimeter and area of the original and enlarge it figure
The perimeter and area of the original are 20 ft and 23.5 square ft and the enlarged figure are50 ft and 146.875 square ft.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The figure is the combination of a triangle and a square.
The area of the original (A₀) figure will be
[tex]\rm A_o = \dfrac{1}{2} \times 3 \times 5 + 4 \times 4\\\\A_o = 23.5 \ ft^2[/tex]
The perimeter of the original figure (P₀) will be
[tex]\rm P_o = 3 + 5 + 4 + 4 + 4\\\\P_o = 20 \ ft[/tex]
The scale factor is 2.5.
Then the dimension of the triangle will be
h = 2.5 × 3 = 7.5 ft
b = 2.5 × 5 = 12.5 ft
Then the dimension of the square will be
a = 2.5 × 4
a = 10 ft
The area of the new figure will be
[tex]\rm A = \dfrac{1}{2} \times 7.5\times 12.5 + 10*10\\\\ A = 146.875 \ ft^2[/tex]
The perimeter of the new figure will be
[tex]\rm P= 7.5 + 12.5 + 10+ 10+ 10\\\\P = 50 \ ft[/tex]

Answer:
To find the perimeter of an enlarged figure, you can multiply the original figure’s perimeter by the scale factor. You could also multiply each dimension of the original figure by the scale factor to find the dimensions of the enlarged figure, and then add to find the perimeter.

The economy of Rayton can be described by the following statistics:
Current real GDP = $10,000
Full employment real GDP = $12,000
Tax revenue = $3000
Government transfer payments = $1000
Government spending = $3000
a) In what stage of the business cycle is the Rayton economy? Explain.
b) What is the current budget balance in Rayton? Show your work.
c) Senator Fullington, an influential politician in Rayton, has argued that the budget must be
balanced. How could this be accomplished? How would balancing the budget affect real GDP in
Rayton?
Based on the current real and the full employment real GDP, Rayton's economy is at a Recession stage.
The current budget balance in Rayton is -$1,000. The budget can be balanced by reducing government spending or increasing taxes. Both of these would decrease real GDP.
What does the economic data on GDP show?The fact that the current real GDP is less than the full employment GDP shows that the nation is at a recession stage where it is underperforming.
What is the current budget balance?This can be found as:
= Government revenue(taxes) - government spending
= 3,000 - 1,000 - 3,000
= -$4,000
In order to make a balanced budget where government revenue will equal government spending, the government either needs to reduce spending or increase revenue ( taxes ).
Increasing taxes or reducing spending, will lead to less money available for spending in the economy which will lead to a decrease in real GDP.

What is the value of x?
Answer: 44
Step-by-step explanation:
Find the equation of the tangent line to the curve y=
The equation of the tangent line to the given curve (which is parallel to line (2x−y+9=0) is y−2x−3=0.
What is the equation of tangent?There are two important elements to finding an equation that defines a tangent line: its slope and its point of contact with a curve.
The equation of the given curve is;
[tex]\rm y=x^2-2x+7[/tex]
On differentiating with respect to x, we get:
dx/dy=2x−2
The equation of the line is;
2x−y+9=0
y=2x+9
The slope of the line =2
If a tangent is parallel to line 2x−y+9=0, then the slope of the tangent is equal to the slope of the line.
Therefore, we have:
2=2x−2
2x=4
x=2
Now, at x=2
y=22−2×2+7=7
Thus, the equation of the tangent passing through (2,7) is given by,
y−7=2(x−2)
y−2x−3=0
Hence, the equation of the tangent line to the given curve (which is parallel to line (2x−y+9=0) is y−2x−3=0.

Answer:
Step-by-step explanation:
Problem 12
Comment
A cyclic quadrilateral (a 4 angled quadrilateral where all 4 corners touch the circumference of a circle), has the property that opposite angles add up to 180 degrees.
Formula
4x + 9 + 3x + 3 = 180 Collect like terms
Solution
4x + 3x + 9 + 3 = 180 Combine
7x + 12 = 180 Subtract 12 from both sides
7x + 12 -12 = 180 - 12 Combine
7x = 168 Divide by 7
7x/7 = 168/7
x = 24
Answer
x = 24

6x - 30 = 180 Add 30 to both sides
6x -30+30 = 180 + 30
6x = 210 Divide by 6
