The answer is 4. Is it right?
Answer:
v₁ = 2.5; v₂ = 0.5.
Step-by-step explanation:
4v² + 8v + 5 = 10
4v² + 8v + 5 - 10 = 10 - 10
4v² + 8v - 5 = 0
D = 8² - 4 · 4 · (-5) = 64 + 80 = 144

Answer:
x < -15
Step-by-step explanation:
-1x + 5 < 20
- 5 - 5
-1x < 15
/-1 /-1
x < -15
Answer:
x=0 x=3 x=-2
Step-by-step explanation:
p(x)= 3x^3 – 3x^2– 18x
Factor out the greatest common factor, 3x
p(x)= 3x (x^2 – x– 6)
Factor inside the parentheses
What 2 numbers multiplies to -6 and adds to -1
-3*2 = -6
-3+2 = -1
p(x)= 3x (x-3)(x+2)
Setting the function equal to zero to find the zeros
0 = 3x (x-3)(x+2)
Using the zero product property
3x = 0 x-3 =0 x+2 =0
x=0 x=3 x=-2
When a figure is dilated, this means the corresponding sides of the shape is enlarged in a uniform multiple. In thsi case, the ratio of the sides remains the same. Thus, when ratio of the sides remains the same, the corresponding angles are also congruent in the dilated figure.
