Frank tried to solve an equation step by step. -5=5(d+4)

-5=5d+20 Step 1
15=5d Step 2
3=d Step 3

Find Frank's mistake

a) Step 1
b) Step 2
c) Step 3
d) Frank did not make a mistake

step 2 is wrong

there should be -25 instead of 15

Hope it helps

please mark brainliest

B

Step-by-step explanation:

when grouping the like terms the 20 will become a negative therefore -20-5 is -25 so the 5d has to be divided into -25 and not 15.. making the rest of the answer wrong.

-5-20=5d

-25/5=5d/5

-5=d

I hope this helps

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

i think it is c, not positive though
