What is the solution to –2(5y – 5) – 3y ≤ –7y + 22?
Gre4nikov [31]
-2(5y - 5) - 3y < = -7y + 22
-10y + 10 - 3y < = -7y + 22
-13y + 10 < = -7y + 22
-13y + 7y < = 22 - 10
-6y < = 12
y > = -12/6
y > = -2....answer B

Answer:

230.5

Step-by-step explanation:

Formulas: a = 1/2(bh), a = bh

Rectangle 1: a = 6 x 8

a = 48

Base of the triangle: 9 + 6

15

Triangle 1: a = 1/2(15 x 24)

a = 180

Triangle 2: a = 1/2(4(13 - 8))

a = 2.5

48 + 180 + 2.5

230.5

<u>The area of the figure is 230.5.</u>

If this truly helps you out, help me out too and thank me or maybe even mark brainliest.

You have a square that has a side length of $1$ centimeter. Each minute, $2$ centimeters are added to the side length. After $10
Mariulka [41]

Answer:

Difference in area of the last square and the initial square = 440 cm²

Step-by-step explanation:

Length of the side of a square = 1 cm

Area of the square = (side)² = 1 cm²

Addition of side length every minute = 2 cm

After x minutes length of each side of the square = (1 + 2x) cm

If x = 10 minutes

Length of each side of the square = [1 + 2(10)]

                                                         = 21 cm

Area of the square after 10 minutes = (21)²

                                                            = 441 cm²

Therefore, difference in area of the last square and area of the initial square

= 441 - 1

= 440 cm²
