Answer:

Combine like terms onto one side of the equation

Step-by-step explanation:

You have

-x^2  -4x  - 3  = 2x + 5

It seems that we should combine like terms to make this equations smaller.

-x^2 - 4x - 3  - 2x  - 5 = 0

-x^2  -6x  - 8 = 0

- (x + 2)(x + 4) = 0

x = -2  or  x  = -4

Answer:

16, 60, 20

Step-by-step explanation:

This is an equilateral triangle and since the LN is 16, LM must be as well.

The second, again is equilateral, so the angles must all be 60 degrees.

The last question is equilateral so all angles are equal to 60, and 60/3 is equal to 20.

Write a polynomial with the zeros equaling to -1,1,8
Andreyy89

Answer:x³-8x²-x+8

Step-by-step explanation:

x are equal to -1,1,8 respectively

to form the polynomials just simply use this method put (x-)to the given numbers that are zeros of the polynomials

(x-(-))(x-1)(x-8)

(x+1)(x-1)(x-8) →(x+1)(x-1) are diff. of two squares (x²-1)

(x²-1)(x-8)

x²(x-8)-1(x-8)

p(x)=x³-8x²-x+8
