Vlad [161]2 years ago
5 0

Answer:

P = 106

A = 330

Step-by-step explanation:

= 2(l+w) (perimeter of rectangle)

= 2·(18+15)

= 66

picture below of perimeter of right angle triangle

Add both values

P= 66 + 40

P = 106

= w*l (Area of rectangle)

=15·18

= 270

= ab/2 ( Area of triangle )

= 8·15/2

=60

Add both values

A = 60 + 270

A = 330

I hope it helps

Solve for x 2x +3y = Q
Marianna [84]

Hello! :)

2x + 3y + −3y = q + −3y Add -3y to both sides

2x = q − 3y

2x/2 = q-3y/2 Divide both sides by 2

x = 1/2q + -3/2 y (ANSWER)

Hope this helped you

Can someone please help me on this problem and show work pleasee I’m having trouble doing this!!!
Katarina [22]

Let’s start by stating the formula for the area of a rectangle,

A=LW

the letter a represents area, l represents length, and w represents width.

Next let’s substitute known values.

A=x(x+10)

Next let’s use the distributive property

A=(x(x))+(10(x))

Now simplify.

A=x^2 + 10x

So the equation for the area of this rectangle is A=x^2+10x

I believe this is the most simplified answer, please tell me if I am wrong and I will redo my work.
