15x²+16x+4 =0 (ax² +bx +c=0)
Δ = b²-4ac =256 - 4×15×4 =16
x1 = (-b+√Δ) / 2a = (-16+√16) / 30 =( -16+4) / 30 = -12/30 = - 2/5
x2 = (-b -√Δ) / 2a = (-16 -√16) / 30 = (-16 -4) /30 = -20/30 = -2/3
Answer:
185/24
Step-by-step explanation:
Convert both to fractions with the same denominator first.
35/8= 105/24
10/3= 80/24
105/24+80/24
= 185/24
Answer:
x < -2
Step-by-step explanation:
12 - 6x > 24 Equation
-6x > 12 Subtract 12 from both sides
x < -2 Divide both sides from -2, if you divide by any negative number in an inequality you have to switch the sign
I can’t see can you put it closer
