Answer:

6x^2 - 10x inches ^2

Step-by-step explanation:

The area of a rectangle is

A = l*w

= (3x-5) * (2x)

= 6x^2 - 10x

Answer:

The area of the rectangle is 6x^2(squared)-10x

Step-by-step explanation:

To find the area of rectangles, you must multiply the length by the width. The formst for this is A=LxW. When you substitute each part of the equation in, it becomes 2x(3x-5). When you have parentheses, distribute the number on the outside to each number(or variable) on the inside. First, multiply 2x by 3x. This leaves you with 6x^2(squared). Then, multiply the 2x by the -5. This leaves you with -10x. Combine each part to get 6x^2(squared)-10x. :)

Answer this please !

Answer:

Step-by-step explanation:

$\frac{y}{2} =x^{2} -7$

$\frac{a}{2} =2^{2} -7$

$\frac{a}{2} =-3$

$a=-6$

$\frac{b}{2} =1^{2} -7$

$\frac{b}{2} =-6$

$b=-12$

From the calculations above, we learn that line l and the curve intersect at (2, -6) and (1, -12). Next, we will set up a system of linear equations to solve for the slope and the y-intercept of line l.

$-6=2m+b$

$-12=m+b$

$-24=2m+2b$

$18=-b$

$b=-18$

$-12=m-18$

$m=6$

Therefore, the slope of line l is 6.

How do you find the probability? give me details please and answer my question step by step.

mart [117]

Answer:

to find theoretical probability, devide the favorable outcomes by the total possible outcomes

to find experimental probability, for example on a coin, devide how many times it landed on heads by how many times you flipped it

i hope this helps :)

You score 15 16 17 14 and 19 points out of 20 possible points that I test what must you score on the 6th test to have average of

Lelu [443]

Hello! To find the answer to this, we must add all of the first 5 numbers. When you do that, the sum should be 81. You must do 16 * 6 to find the number of points combined he needs to add up to the average. 16 * 6 = 96. 96 - 81 = 15. On the 6th test, you must score 15 points to have an average of 16 points. The answer is 15.
