To factor x^2 + 2x - 8 follow these steps

1) Write to factors, with x as the first term, this way:

(x )(x )

2) The sign to the right of the x in the first factor is the same sign of the coeficient of x in the polynomial.

That is +.

The sign to the right of the x of the second factor is the product of the sign of the coefficent of x (this is +) and the sign of the independent term (this is - ).

So that is (+).(-) + -.

Now the two factors have this form:

(x + ) (x - )

3) Now find two numbers whose product is - 8 and whose difference is +2

Those numbers are + 4 and -2.

Then the two factors are:

(x + 4) (x - 2).

So the answer if that the correct factorization is (x + 4) (x - 2)

Daisy, the african elephant weighs 10,250 pounds. The daily feed intake for an elephant is approximately 1.5% of the animals bod

AlexFokin [52]

Answer: a) 154 kilograms

Step-by-step explanation:

Given : Daisy, the african elephant weighs 10,250 pounds.

The daily feed intake for an elephant is approximately 1.5% of the animals body weight.

1.5% can be written as 0.015.

Now, the amount of feed is to be feed to Daisy to meet her requirements will be :_

$0.015\times10250=153.75\approx154$

Hence, 154 kilograms of feed is to be feed to Daisy to meet her requirements.
