What is the solution to the equation 4 + 3sqrt 2y = 6?
mojhsa [17]

Answer:

4+3√2y = 6

3√2y = -4+6

3√2y = 2

(3√2y)2 = (2)2

18y = 4

Add 4 to both sides

18y = 4

Divide both sides by 18

A possible solution is :

y = (2/9)

What is the surface area?
Ratling [72]
The formula for the surface area of a rectangular prism is

A= 2(wl+hl+hw)

We are given the height =2cm, width= 5cm, and length= 10cm. All you have to do is plug this info in!

A= 2(wl+hl+hw)
= 2[(5)(10)+(2)(10)+(2)(5)]
= 2(50+20+10)
= 2(80)
=160 cm squared

Hope this helps!! :)
