Someone please help me with this question

mrs_skeptik [129]

Answer:

10x

Step-by-step explanation:

By definition

$(f\codt g)(x)=f(x)\cdot g(x)$

So we just need to multiply the two functions

$(f\cdot g)(x)= f(x)\cdot g(x)\\=\sqrt{2x}\cdot \sqrt{50x}\\=\sqrt{(2x)\cdot (50x)}=\sqrt{100x^2}\\=10\sqrt{x^2}\\=10x \text{ since x is non negative}$

-4(x+1)-3=-3(x-4) solve for x please. Giving brainliest

Sophie [7]

Answer:

-19 = x

Step-by-step explanation:

Step 1: Write equation

-4(x + 1) - 3 = -3(x - 4)

Step 2: Solve for x

Distribute: -4x - 4 - 3 = -3x + 12

Combine like terms: -4x - 7 = -3x + 12

Add 4x on both sides: -7 = x + 12

Subtract 12 on both sides: -19 = x
