Answer:

-x-3, 7x-3, -15

Step-by-step explanation:

For first 2 just add/subtract their equations. For the last one (r.s)(-1) is the same as r(s(-1)) so s(-1)=4(-1)=-4 and r(-4)=3(-4)-3=-12-3=-15

The equivalent expressions of 22c + 33d are (a), (c) and (e)

<h3>How to determine the equivalent expressions?</h3>

The expression is given as:

22c + 33d

Factor out 11 from the expression

11(2c + 3d)

Multiply by 1

1 * 11(2c + 3d)

Express 1 as -1 * -1

-1 * -1 * 11(2c + 3d)

Evaluate the product

(-11) * (-2c - 3d)

Also, we have:

22c + 33d

Multiply by 1

(22c + 33d) * 1

Express 1 as 3/3

(22c + 33d) * 3/3

Evaluate the product

(66c + 99d) * 1/3

Hence, the equivalent expressions are (a), (c) and (e)

find the perimeter and total area of the composite shape shown below. All measurements are given in inches. Use pie=3.14 in any
kozerog [31]

Square part of perimeter = 40.

Half circle = 25.135.

Together 65.135 is perimeter.

Area of square: 192

Are of half circle: 100.53.

Together 292.53

Rounded =292.48 I guess, its the most logical option since I don't see it and the only one that fits perimeter answer.

So its the 3rd question I believe, you may want to double check.

Hit the heart if it was helpful.

A chicken recipe calls for 1/4 T of paprika for each 1/2 T of garlic powder. If you use 3/4 T of paprika, how much garlic?
LuckyWell [14K]

Answer:

1 1/2 T garlic

Step-by-step explanation:

You used 3 times as much paprika as the recipe asks for. Therefore, to keep the ratio the same, you also have to multiply the amount of garlic by 3. So, you need 3/2 or 1 1/2 T of garlic.
