Answers
Answer:
Length = 7cm
Breadth = 4cm
Step-by-step explanation:
The shape of the room is original my in a square shape
Area of a rectangle = Length × Breadth
Area = 28 cm²
Length = L - 1
Breadth = B + 2
Hence
28 = (L - 1)(B + 2)
b(b + 3) = 28
b² + 3b = 28
b² + 3b - 28 = 0
b² +7b - 4b - 28 = 0

So all you have to do is multiply the radius by itself. So in this case 14x14=196.
So then multiply that by pi aka 3.14. So 196x3.14=615.44 then multiply that by your height in this case its 7 So 615.44x7=4308.08

You are familiar with buying items in shops and markets but often, when buying expensive goods, different methods of payment are available.
You might be offered a hire purchase agreement: you would pay a deposit and then pay the remainder of the cost of the item in a specified number of (often monthly) instalments. In a sale, the cash price might be reduced.
You need to remember that most goods are subject to a government sales tax, often referred to as VAT (value added tax). In Jamaica this government tax is GCT (general consumption tax) which is currently charged at 16

Um vendedor de frutas saiu com 372 bananas se eu voltar para casa trazer 129 bananas quantas bananas ele vendeu operação e resposta?
Answers

Número inicial de bananas = 272
Número de bananas devolvidas com = 129

Portanto, número de bananas vendidas:
372 - 129 = 243
Anita needs to construct ten cones for a class project. How many square feet of material will she need? Use 3.14 for π. Enter your answer in the box. Th radius is 6 ft and the height is 12 ft.
Answers
Assuming that Anita needs hollow right circular cones, we are solving for its lateral surface area, which is given by the formula πr√ (h²+r²), where r is the radius and h is the height.
r = 6 ft / 2 = 3 ft
Solving for the lateral surface area of one cone:
LSA = (3.14) (3) [√ (12²+3²) ] = 116.52 sq ft.
Since she needs 10 cones:
10 * 116.52 sq. ft = 1,165.2 sq ft.
She will need 1,165.2 sq ft of material.
Hope this helps you :)

Solving like terms
-17x - 8
If you want to find the value of x then
-17x - 8 = 0
-17x = 8
x = 8/-17
Answer: -17x - 8
Step-by-step explanation:
First, we distribute the -4 into the parenthesis:
-4(3x + 2) - 5x
-12x - 8 - 5x
Now, we combine like terms:
-12x - 8 - 5x
-17x - 8

What is the area in square meters of the trapezoid below
Answers
Answer:
69.3 meters squared
Step-by-step explanation:
1) Think of the shape as being divided into two sections (a rectangle and a triangle)
2) multiply 5.2 times 7 to find the area of the rectangle (36.4)
3) subtract 5.2 from 14.6 to find the base of the triangle (9.4)
4) multiply 9.4 by the height of the triangle 7 (65.8)
5) divide 65.8 by two because a triangle is half of the needed rectangle
6) this leaves 32.9
7) add 32.9 and 36.4 to get your final answer of 69.3 meters squared
hope this helps :)
