Answer:

1. (x+5)(x-1)

6. (3x+4)(x-6)

9. (x+5)(x-5)

Step-by-step explanation:

To factor an equation, break the polynomial into two binomials which multiply to make it. There are three main ways to factor:

Regular: Find two numbers that multiply to C and add to B from $ax^2 + bx + c$ .

$x^2+4x-5 = (x+5)(x-1)$

Grouping: Find two numbers that multiply to A*C and add to B. Then split B into the two factors and factor by GCF.

$3x^2-14x-24\\3x^2 - 18x + 4x - 24\\(3x^2-18x)+(4x-24)\\3x(x-6)+4(x-6)\\(3x+4)(x-6)$

Difference of Squares: Factor by taking the square root of each term. $a^2-b^2 = (a-b)(a+b)$

$x^2 - 25 = (x+5)(x-5)$

Victoria completed 1/8 of her test in 2/5 of an hour if it koreas rate stayed the same how much of her test was finished in 1 ho

dangina [55]

Answer:

Step-by-step explanation:

Step one:

given

let the total amount of her test be x

we are told that she complete 1/8x test in 2/5 of an hour

hence she completed 1/8x in 0.4 hours

let us find the rate at which she completes are test

rate= 1/8x/0.4

convert the numerator to decimal number for easy computation

rate= 0.125x/0.4

rate=0.3125x per hour

Step two:

Hence 1 hour she can finish 0.3125x *1

=0.3125x

She can finish 31.25 % of her test in 1 hour

or 1/16 of her test

Find the indicated values where g(t)=t^2-t and f(x)=1+x g(f(0))+f(g(0))

Blababa [14]

Answer:

Step-by-step explanation:

First find f(0) and g(0). These are the values where x=0 in each function.

f(0) = 1+0 = 1

g(0) = 1^2 - 1 = 1-1 = 0

So f(0) = 1 and g(0) = 0.

Now substitute f(0) = 1 into g(t).

g(1) = 1^2 -1 = 1-1 = 0.

So g(f(0)) = 0.

Now substitute g(0) = 0 into f(t).

f(0) = 1 + 0 = 1.

So f(g(0)) = 1.

Add the values 0 and 1 to get 0+1 = 1.
