1 answer:

7 0

Hello
let : f(x) = 6 + √(14+x) - <span>√(9x)
f(2) = </span>6 + √(14+2) - √(9×2)
f(2) = 6 + √(16)-√(18)
f(2) = 6 + 4 - √(18) = 10 - √(18)

Answer: hewo, there! your answer is below

x= -5/4

or x= 8

Step-by-step explanation:

step 1: Subtract 27x+40 from both sides.

4x2−(27x+40)=27x+40−(27x+40)

4x2−27x−40=0

Step 2: Factor left side of equation.

(4x+5)(x−8)=0

Step 3: Set factors equal to 0.

4x+5=0 or x−8=0

hope this helps you

9. If the area of square 1 is 250 units?, and the area of square 3 is

Aleks [24]

Answer:

185 units.

Step-by-step explanation:

So first, I subtracted: 250 - 120 = 130

I divided 130 by 2. I got 65.

I subtracted 65 from 250 and I got 185.

Proof it is correct:

185 - 120 = 65

AND

250 - 185 = 65
