You can solve by using Pythagoras theorem.
Let the longest side be c.
a^2 + b^2 = c^2
If this holds, it is a right angle.

But, 3.5^2 + 4.5^2 is not equal to 5.5^2.

I don't know.
Let's find out.
If it IS a right triangle, then . . .

    (square of the shortest side)
plus
    (square of the medium side)
adds up to
    
(square of the longest side).

Shortest side = 3.5 .  Its square is  (3.5)²  =  12.25
Medium side = 4.5 .  Its square is  (4.5)²   =  20.25
(square of the shortest side) + (square of the medium side) =  32.5 .

Longest side = 5.5 .  Its square is  (5.5)²   =  30.25 .

  30.25  is NOT equal to  32.5 .

  So this is NOT a right triangle.

A rectangle has perimeter 20 m . Express the area of the rectangle as a function of the length of ones its side.
kondor19780726 [428]

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

How do you solve this 3x-4=3x-5
Basile [38]
Combine like terms so 3x + 3x= 6x
Then put the minus signs with the 4 and 5 and add them together so -4+ -5= -9
Now you have 6x=-9 So you divide by 6 on both sides canceling out 6
but 9 divided by 6 doesn't go into a specific number therefore it has no solution which is a possible answer

2(a-2)=3(a-5) Distrubutive Property
Brrunno [24]
So in distributive property you multiply the outside number by the two inside so in this case 2(a) + 2(-2) = 3(a) + 3(-5)
Which will give you
2a+ - 4 = 3a + - 15
Or
2a-4=3a-15
Then if your solving for a your can subtract 3a from 2a giving you
- a-4=-15
Then add 4 to - 15
-a =-11
Then divide by negative 1 (this is so a isn't negative)
A=11
Hope this helps!
