1 pound equals 16 ounces.
Convert the weight from pounds to ounces.
2 pounds 3 ounces:
2 pounds x 16 ounces per pound = 32 ounces
32 + 3 = 35 total ounces
Now find the difference by subtracting:
56 ounces - 35 ounces = 21 ounces
The kitten gained 21 ounces ( 1 pound 5 ounces)

Answer: About 80 yards
Step-by-step explanation:
From A to B =20 yards (same for E and D) right there you already have 40 yards. Every 2 units 10 yards. F to A is the same length of half of A (10 yards). If you add them all together the perimeter is about 80 yards.
Answer: 85
Step-by-step explanation:
Writing an Equation
Find the length of each side and add them up to get the total perimeter.
We know that there are 6 sides, AB, BC, CD, DE, EF, and FA
We also know that AB = ED and BC = CD = EF = FA
So the total perimeter would be AB + BC + CD + DE + EF + FA = 2AB + 4BC
Finding length of AB
This line goes from (-2,2) to (2,2) so we can find the length by subtracting the x coordinates since the y coordinates are the same
AB = 2 - (-2) = 4
Finding length of BC
Using the Pythagorean Theorem, we can find the length of BC
This line goes from (2,2) to (3,0)
The vertical distance (a) is |0-2| = 2
The horizontal distance (b) is |3-2| = 1
So
Total length
Using the equation 2AB + 4BC to find the perimeter we get
=
=
=
Since is approximately 9, we'll substitute in 9 (assuming we don't have a calculator)
≃ 8 + 9
= 17 units
Converting units
Each unit is 5 yards, so use this ratio get the perimeter in yards
17 units * 5 = 85 yards

The actual dimensions of Laurie’s garden will be 10 feet by 21.25 feet. Then the correct option is D.
What is dilation?
Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.
Laurie will draw a scale model of the garden she wants to plant. Her scale will be 1 cm = 2.5 ft. Then the scale factor will be 2.5 feet per cm.
The dimension of the garden will be 8.5 cm by 4 cm. Then the actual dimensions of Laurie’s garden will be
Length = 8.5 x 2.5
Length = 21.25 feet
Width = 4 x 2.5
Width = 10 feet
The actual dimensions of Laurie’s garden will be 10 feet by 21.25 feet. Then the correct option is D.
