Find x AND the length of each side if ABC is an isosceles triangle with AB = BC . (Answers Rouen to the nearest tenth if needed)
Answers
Answer:
x = 7
AB = 7
BC = 7
Step-by-step explanation:
AB = BC cuz it's an isosceles triangle
In the given isosceles triangle x is 7 units and AB ≅ BC is also of 7 units.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
As the triangle has two equal sides we can equate two expressions to find x.
∴ 2x - 7 = 4x - 21.
- 2x = - 14.
2x = 14.
x = 7.
AB = 2(7) - 7.
AB = 14 - 7.
AB = 7.
BC will also be of 7 units as AB ≅ BC.

What does this equal too(2x-5)^2
Answers
Answer:
4x² - 20x + 25
Step-by-step explanation:
(2x-5)² means (2x-5)(2x-5)
Expand the brackets.
1. do 2x times 2x = 4x²
2. do 2x times -5 = -10x
3. -5 times 2x = -10x
4. -5 times -5 = 25
Altogether it is 4x² - 10x - 10x + 25
This simplifies to 4x² -20x + 25.
A community hall is shape of a cuboid. The hall is 40 m long, 15 m wide and 3 m high. The community hall needs re-decorating with new point for the walls and ceiling, and new tiles on the floor. A 10 litre tin of paint covers 25m*25m and costs £10. 1m*1m floor tiles cost £3 each. Work out the total cost of paint and tiles needed to re-decorate the community hall.
Answers
Step-by-step explanation:
We have been given that a community hall is in the shape of a cuboid. The hall is 40m long 15m high and 3m wide.
The paint will be required for 4 walls and ceiling.
Let us find area of walls and ceiling.
Therefore, the area of walls and ceiling is 1410 square meters.
Given: Cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. Therefore,
Therefore, the total painting cost is $564.
Tiles will be required for floor. Let us find the area of floor.
Given: 1m squared floor tiles costs $3. So,
Therefore, the total cost for tiles is $360.
Now let us find combined total cost of tiles and paint.
Therefore, the combined total cost of tiles and paint is $924.

if Afsheen can read 39 pages of a book in half an hour how much will it take her to finish the book that is 1287 pages
Answers
We are given:
Afsheen can read 39 pages in 30 minutes
Time taken by Afsheen to read 1287 pages:
Time taken to read 1 page:
Time taken to read 1 page = time taken to read 39 pages / 39
Time taken to read 1 page = 30 minutes / 39
Time taken to read 1 page = 0.77 minutes
Time taken to read 1287 pages:
Time taken to read 1287 pages = Time taken to read 1 page * 1287
Time taken to read 1287 pages = 0.77 * 1287
Time taken to read 1287 pages = 991 minutes OR 16.52 hours (Approx)
Answer:
in 1 hour = 2×39= 78 pages
so 1287 pages= 1287÷78= 16.5 hours
Step-by-step explanation:
it takes 16. 5 hours that means 16 hours 30 min
