Regina has started making baby quilts to sell at a craft fair. The inside of each quilt will measure four feet by five feet and

will be surrounded by a border of uniform width. She wants each quilt to have a total area (including the border) of 30 square feet. Find the equivalent equations to find the width of the border given that the border is x. Select all that apply.
1: (4+x)(5+x)=30
2: (4+2x)(5+2x)=30
3: 4x^2 + 20 = 30
4: 4x^2 +18x+20=30
5: (5+x)(4+x)=30
6:(x+4)(x+5)=30

Given are the statements describing the area of the baby quilts:

Inside dimensions = 4 x 5 feet
Border with uniform width = x feet
Total area of the quilt = 30 square feet

A = length x width

Area of inside quilt = 4 x 5
Area of quilt including the border = (4+2x) * (5+2x)

Therefore, the equations that are applicable are:

<span>2: (4+2x)(5+2x)=30
</span><span>4: 4x^2 +18x+20=30</span>

Which expressions are equivalent to 4b ?
aivan3 [116]

Answer:

They are b and c.

Step-by-step explanation:

Let's simplify each expression:

a. b+2 (b+2b)

= b + 2b + 4b = 7b.

b.  3b + b = 4b.

c. 2(2b) = 2 * 2b = 4b.

∆ABC has A(-3, 6), B(2, 1), and C(9, 5) as its vertices. The length of side AB is units. The length of side BC is units. The len
leonid [27]

Answer:

AB = 7.07 units

BC = 8.06 units

AC = 12.04 units

Step-by-step explanation:

To find the length for each side of the triangle, apply the distance formula between each pair of vertices.

<u>AB</u>

d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\d = \sqrt{(2--3)^2 + (1-6)^2} \\d = \sqrt{(5)^2 + (-5)^2} \\d = \sqrt{25 + 25} \\d = \sqrt{50} \\d=7.07

<u />

<u>BC</u>

d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\d = \sqrt{(9-2)^2 + (5-1)^2} \\d = \sqrt{(7)^2 + (4)^2} \\d = \sqrt{49 + 16} \\d = \sqrt{65} \\d=8.06

<u />

<u>AC</u>

d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\d = \sqrt{(9--3)^2 + (5-6)^2} \\d = \sqrt{(12)^2 + (-1)^2} \\d = \sqrt{144 + 1} \\d = \sqrt{145} \\d=12.04

25 ounces of guacamole are still expected to be available from batch.

Step-by-step explanation:

Given,

Quantity of guacamole in one serving = 2.2 ounces

Quantity of guacamole in one batch = 80 ounces

Quantity of guacamole in 25 servings = 2.2*25 = 55 ounces

Guacamole left = Quantity in batch - Quantity of 25 servings

Guacamole left = 80-55 = 25\ ounces\\

25 ounces of guacamole are still expected to be available from batch.
