Answer:
x² + x + 8 = 0
Step-by-step explanation:
Given
(x - 2)² + 5(x + 2) - 6 = 0 ← expand (x - 2)² and distribute parenthesis by 5
x² - 4x + 4 + 5x + 10 - 6 = 0 ← collect like terms on left side
x² + x + 8 = 0 ← equivalent quadratic equation
1 km^2 = 1000m x 1000m = 1 x 10^6 m^2
<span>(145 acres / 247 acres) x 1 x 10^6 m^2 = 5.87 x 10^5 m^2 </span>
<span>5.5 g/m^2 x 5.87 x 10^5 m^2 = 3.23 x 10^6 g </span>
<span>3.23 x 10^6 g x 1kg/10000 g = 3.23 x 10^3 kg</span>
Answer:
y = ⅔(x²)
Step-by-step explanation:
After vertical stretch of f(x), it becomes a×f(x) where a is the factor
Therefore,
New parabola: y = ⅔(x²)
Let us say, the numbers are "a" and "b"
their sum is -13
a + b = -13
their product is 40
a * b = 40
solve for "a",
what is "b"? well, b = 40/a :)
The mistake he made was that he multiplied 2 and 3, equaling 6. But what he SHOULD have done was multiply 2 * 2 * 2 to get 8
