Find a quadratic equation whose roots are -3 and 5
Answer:
x² - 2x - 15 = 0Step-by-step explanation:
Roots:
x₁ = -3, x₂ = 5The equation:
(x - x₁)(x - x₂) = 0(x - (-3))(x - 5) = 0(x + 3)(x - 5) = 0x² + 3x - 5x - 15 = 0x² - 2x - 15 = 0Step-by-step explanation:
Let the roots be a and b
a=-3b=5To form a equation the formula is
[tex]\sf x^2-(a+b)x+ab[/tex]
[tex] \sf➡ {x}^{2} - ( - 3 + 5)x + ( - 3)5 \\ \sf \: ➡ {x}^{2} - 2x - 15 = 0[/tex]

As an estimation we are told 5 miles is 8 km.
Convert 55 miles to km
Answer:
88 km.
Step-by-step explanation:
If 5 miles is 8 km,
55 miles is 88 km.
What you need to do is 55/5 = 11.
Then multiply that 11 to 8.
11 * 8 = 88.
Basically, if you are multiplying 5 by 11 to get 55, you need to multiply 8 by 11 to get 88.

(PLEASE HELP) Find the product of
(x+4)(x2+7x).
Answer:
x³ + 11x² + 28x
Step-by-step explanation:
(x + 4)(x² + 7x)
Each term in the second factor is multiplied by each term in the forst factor, that is
x(x² + 7x) + 4(x² + 7x) ← distribute parenthesis
= x³ + 7x² + 4x² + 28x ← collect like terms
= x³ + 11x² + 28x
[tex] \huge \underline{ \sf \: Solution}[/tex]
[tex](x + 4)( {x}^{2} + 7x) \\ = x( {x}^{2} + 7x) + 4( {x}^{2} + 7x) \\ = {x}^{3} + {7x}^{2} + {4x}^{2} + 28x \\ = {x}^{3} + {11x}^{2} + 28x [/tex]
