Please can anyone help with this.

Step-by-step explanation:

As it is right angle, we can use Pythagoras theorem.

x² + 48² = 50²

x² + 2304 = 2500

x² = 2500 - 2304

x² = 196

x = √196 = √14*14

x = 14

answer: it is a.,b.,d.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
