Help me plssssssssssssssssssssssssssssss
Naddika [18.5K]

Answer: See explanation (btw, the answer is always in bold letters)

Step-by-step explanation:

1.) 1 gallon for $1.99

1/2 gallon for $0.98

1 gallon would be 0.98 × 2 = <em>1.96</em>

2 gallons for $3.98

1 gallon would be 3.98 ÷ 2 = 1.99

2.) 621 ÷ 4 = 155.25

He pays $155.25 each payment!

3.) V = s³

s = 3

V = 3³

3 × 3 × 3 = 27

V = 27 m³

4.) This is a rectangle; the area of a rectangle is l × b.

L = 6.9

l × b = a

6.9b = 28.29

Divide both sides by 6.9

b = 4.1

The missing length is 4.1 m

5.) False

In a triangle shown, which shows the correct order of the side lengths from smallest to largest.
Vera_Pavlovna [14]

Answer:

Not sure if there are options, but the order of side lengths from smallest to largest is <u>j, k, l</u>

Step-by-step explanation:

This is a bad explanation (sorry):

Side length order will be the same order of angle orders. By that, I mean the since angle C has the smallest angle, the side length across from it will also be the smallest. Since angle B is the biggest angle, side L will be the biggest length. This leaves angle A (and side k) in the middle.

Please help me, I will be so thankful ​
worty [1.4K]

Answer:

Step-by-step explanation:

g(-4) = 4   ,  x < -2

g(-2) = (x - 1)²     ; -2≤x< 1

        = (-2-1)²

         = (-3)²

g(-2) = 9

g(0) = (x -1)²      ;  -2 ≤ x < 1

      = (0 -1)²

       = (-1)²

       = 1
