Answer:

c = 2A/w - b

Step-by-step explanation:

The area of a trapezoid can be calculated by using the formula A=1/2w(b+c). Which expression can be used to caculate the length , c, parallel sides to b

A = 1/2 × w (b + c)

Solving for c

Divide both sides by 1/2

A/1/2 = w (b + c)

2A = w (b + c)

Divide both sides by w

2A/w = b + c

Making c the subject of the formula

c = 2A/w - b

The expression that can be used to calculate the length , c, parallel sides to b is :

c = 2A/w - b

What is y=-4/3x +6. y=2
Mekhanik [1.2K]

The given equation is:
[/tex]y=-\frac{4}{3}x+6 [/tex] and we need to evaluate this for y=2.
So, first step is to plug in 2 for y in the above equation. Therefore,

2=-\frac{4}{3} x+6
2*3=-\frac{4}{3} x*3+6*3 Multiply each sides by common denominator 3
6=-4x+18
6-18= -4x Subtract 18 from each sides.
-12=-4x
-\frac{12}{-4} =-\frac{4x}{-4}
So, x=3

A rectangle is 13 centimeters wide and 18 centimeters long. how long is its diagonal
Naddika [18.5K]
You have to use the Pythagorean theorem a squared plus b squared is c squared so 13 squared plus 18 squared equals c squared. 13x13=169 18x18=324 169+324=493 so c squared is 493 to get c you square root 493 which equals 22.2 so the diagonal, c, is 22.2 centimeters long
