Answer:

(x + 4)(x - 3)

Step-by-step explanation:

x^2 + x - 12 = 0

In order to factorise an equation, one must take into consideration the factors of the values in given equation.

In the factored form, the above equation becomes

(x + 4)(x- 3)

Factors of x^2 = x times x

Factors of -12 = +4 x -3

As shown in the factored form above

Answer and Step-by-step explanation:

The answer is H.

$f(x) = \frac{1}{3} (4)^x$

When 4 is brought to the power of a number it gets multiplied to the numerator of 1/3. When inputting those numbers for x in this function, the result is what is shown on the table, meaning the function is correct.

Sergeeva-Olga [200]

Answer:

The wide of river is $50\ ft$

Step-by-step explanation:

In this problem we know that

Triangles DEG and DEF are congruent by ASA (Angle-Side-Angle) Congruence

therefore

EG=EF

$EG=20*(2\frac{1}{2})=20*\frac{5}{2}=50\ ft$

The moon is about 240,000 miles from earth . What is the distance written as a whole number multiplied by a power of ten

Murrr4er [49]

240,000 is a whole number. Now do the power of ten lol. Use a calculator. Remember don't do it all at once. The powers mean multiplying separate for example: 10×10 equals 100. I hundred times10 equals 1000. That is powered by three because it is multiplying 1030 different times which makes it the power. Simple math these days ha ha
