Answer:
x = 3
Step-by-step explanation:
4x+2 = x+11
Subtract x from each side
4x+2-x = x+11-x
3x+2 =11
Subtract 2 from each side
3x+2-2 =11-2
3x = 9
Divide by 3
3x/3 =9/3
x = 3
Can you explain what the question is asking?
Answer:
10. 16 cubic cm
11. 5 and 1/3 cubic cm
Step-by-step explanation:
4 · 4 · 2 = 32
32 times 1/2 = 16
2 · 2 · 4 = 16
16 times 1/3
Answer:
2 real solutions
Step-by-step explanation:
Remember this messy thing?

The <em>quadratic formula</em>, as it's called, gives us the roots to any quadratic equation in standard form (ax² + bx + c = 0). The information on the <em>type</em> of roots is contained entirely in that bit under the square root symbol (b² - 4ac), called the <em>discriminant</em>. If it's non-negative, we'll have <em>real</em> roots, if it's negative, we'll have <em>complex roots</em>.
For our equation, we have a discrimant of (-3)² - 4(6)(-4) = 9 + 96 = 105, which is non-negative, so we'll have real solutions, and since quadratics are degree 2, we'll have exactly 2 real solutions.
Answer:
the answer would be b
Step-by-step explanation:
the other 2 have negatives and the 3rd option is whole so b
