Start by plugging both points within each parenthesis into x and y. Do it interchangeably also!

2(1)+5(1)= 7, which means it isn’t going to prove true. Because 7 isn’t greater than 7.
Since both are 1 it is already interchangeable.

2(-1)+5(4)=-2+20, which is 18. This means the solution doesn’t work, because 7 isn’t greater than 18.

2(4)+5(-1)=8+-5, which is 3. This one must work because 7 is greater than 3!

Answer:

V = 26d^2 + 624d

Step-by-step explanation:

Volume = Width x Depth x Height

V = 26 (d) (d+24)

Now distribute 26

V = 26d(d+24)

Then distribute 26d

V = 26d^2 + 624d

Find the surface area of a cylinder with a base radius of 2 cm and a height of 3 cm.
jek_recluse [69]

Answer: 62.8cm^2

Step-by-step explanation:

The surface area of a cylinder is calculated by 2πrh+2πr2

where π is a constant, given as 3.14; h is the height, given as 3cm and r is radius, given as 2cm.

Therefore, rh = 3 x 2= 6 cm ^2 while r^2 =2 × 2= 4 cm^2.

Slot the values into the formula:

V= 2 (3.14) x 6 + 2 (3.14) x 4

V=37.68 + 25.12

V=62.8cm ^2

I hope this helps
