Answer:

22.5

Step-by-step explanation:

It is very important to use bidmas (the order of mathematical functions - standing for brackets, indices, division, multiplication, addition, subtraction) in this question. 15 + 6 x 7 - 12 divided by 2 can also be written as (15 + 6 × 7 - 12) ÷ 2. First, you should complete the multiplication to make (15 + 42 - 12) ÷ 2. Then, complete the addition which makes (57 - 12) ÷ 2. Afterwards, do the subtraction which makes it 45 ÷ 2. This is 22.5. I hope this helps!

Simplify quantity x squared plus 3 x plus 2 end quantity over quantity x plus 1
Alenkasestr [34]

Answer:

<u>After factorizing the equation on the numerator, we simplify and the answer is: x + 2</u>

Step-by-step explanation:

1. Let's simplify the following expression:

x squared plus 3 x plus 2 over x plus 1

(x ² + 3x + 2) / (x + 1)

Now, we are going to factorize the numerator, this way:

(x + 2) (x + 1) / ( (x + 1)

x * x = x ²; 2x + x = 3x ; 2 * 1 = 2 ⇒ x² + 3x + 2

We simplify (x + 1) both in the numerator and in the denominator and we have:

<u>x + 2</u>

Please help me with this I need it bad

Answer:

1

Step-by-step explanation:

The average rate of change is the gradient _

Gradient = Rise / Run = (y2 - y1) / (x2 - x1)

From the table ;

x2 = 4 ; x1 = - 1 ; y2 = 5 ; y1 = 0

Gradient = (y2 - y1) / (x2 - x1) = (5-0) / (4 - - 1) = 5/5 = 1
