Given 12−(−2) over a line 12−6÷2

We can use PEMDAS rule and solve the expression in the order as given below:-

1. Parentheses

2. Exponents

3. Multiplication

4. Division

5. Addition

6. Subtraction

Now solving for given expression:-

\frac{12-(-2)}{12-(\frac{6}{2})}\\\\=\frac{12+2}{12-3}\\\\=\frac{14}{9}

So final answer is 14/9 i.e. 14 over 9.

Use synthetic division and the remainder theorem to find p(a) = 2x3 -x2 + 10x; = a = 1/2
sergey [27]

Answer:

p(1/2) = 5

Step-by-step explanation:

Find the value of p(1/2) if p(x) = 2x^3 -x^2 + 10x

Set up synthetic div.:

1/2   )   2   -1    10   0

                1      0    5

       ------------------------

           2   0    10     5

The remainder is 5, so we conclude that p(x) = 2x^3 -x^2 + 10x = 5 when x = 1/2.

the length of a rectangle is 9 inches less than twice the width. if the perimeter of the rectangle is 84 inches, find the dimens
Alexus [3.1K]

translate each statement into mathematical language

 

length is nine inches less than twice width.    L = 2W - 9

perimeter is 84 inches                                   2L +2W = 84

 

Substitute the expression for L (2W-9) for L in the second equation resulting in the follwing

 

2(2W-9) + 2W = 84

 

4W - 18 + 2W = 84

 

(4W+2W) = 84+18  

6W =  102

W = 102/6 = 51/3

 

L = 2(51/3) - 9

= L= 17-9

L=6
