I’m pretty sure that the one you marked is correct
Factoring the equation:
3x^2 + 1/2 x 7(3)
3x^2 + 1/2 x 21
3 (x^2 + 1/2 x 21)
3 (x^2 + 7/2)
3 x 1/2 (2x^2 +7)
3/2 (2x^2 + 7)
Answer:
Step-by-step explanation
Hello!
3x/4 + 6=42
3x/4=42-6 = 36
3x = 36*4
3x = 144
x= 144/3 =48
3/4 of 48 = (48*3) / 4 =36
36+6=42
the original number is 48
<span>f(x)=2x+5
then
</span><span>f(4)=2(4) +5 = 8 + 5 = 13
hope it helps</span>
Answer:
