Step-by-step explanation:

A = lw

A=(5x-3)(6x-4)

A=30x^2-20x-18x+12

A=30^2-28x+12

P=2(l + w)

P = 2(5x - 3 + 6x - 4)\\P=2(x-7)\\P=2x-14

Answer:

Perimeter = 22x - 14

Area = 30 {x}^{2}  - 38x + 12

Step-by-step explanation:

Length of rectangle (l) = 5x - 3

Weidth of rectangle (w) = 6x - 4

Perimeter of the rectangle = 2(l + w)

=  > 2(5x - 3 + 6x - 4)

=  > 2(11x - 7)

=  > 22x - 14

Area of the rectangle = l \times w

=  > (5x - 3)(6x - 4)

=  > 5x(6x - 4) - 3(6x -4)

=  > 30 {x}^{2}  - 20x - 18x + 12

=  > 30 {x}^{2}  - 38x + 12

Find the surface area of the trapezoidal
Fofino [41]

Answer:

916 in.

Step-by-step explanation:

Step by Step.

5*10 = 50, and 50*2 = 100

10*4 = 40, and 40 * 2 = 80

(4*6)/2 = 12, and 12 * 2 = 24

10*10 = 100, and 100 * 2 = 200

16*16 = 256, and 256 * 2 = 512

Adding this together, we get: 916 inches.

Omar ordered his sister a birthday card from a company that randomly selects a card from their inventory. The company has 21 tot
Ksju [112]

Answer:

P = 7

Step-by-step explanation:

We have 21 total cards and out of those 21 cards, 14 of those are birthday cards. So that means that the amount of cards that are not birthday cards is the number of cards subtracted by the number of birthday cards, also shown as 21 - 14. So 21 - 14 = P, so now we solve what 21 - 14 is which is 7, so that means P = 7.

Let me know if you have any questions.
