Since length • width = area you need to put the expression with “x” in (parenthesis) and put the number without a variable outside the parenthesis ex: d. would be 5(8-3x) because you would do what’s in the parenthesis first. In this case length is in the parentheses you would have 5(your answer) which means 5•your answer

What are the solutions for x when y is equal to 0 in the following quadratic
lawyer [7]

Answer:

D) x = -12 or x = 2

Step-by-step explanation:

The given quadratic equation is:

y=x^2+10x-24

When y=0, we obtain:

x^2+10x-24=0

We split the middle term with -2, 12 because their product is is -24 and their sum is 10.

x^2-2x+12x-24=0

We factor by grouping to obtain:

x(x-2)+12(x-2)=0

(x-2)(x+12)=0

Either (x-2)=0 or (x+12)=0

Either x=2 or x=-12

Question 7 of 10
sergejj [24]

The product that is  undefined is known a CD, where C is a 3 x 1 matrix and D is a 1 x 2 matrix.

<h3>What is the matrix about?</h3>

Looking at the product of matrix, note that to multiply  the two matrix, the column of the first matrix needs to have the same or equal to the row of the 2nd matrix.

And in this case (propensity), it is not satisfied by the first  option because:

C =  3 x 1  and

O= 2 x 1  matrix

In this case CD is therefore undefined.

So we can say that The product that is  undefined is known a CD, where C is a 3 x 1 matrix and D is a 1 x 2 matrix.
