Step-by-step explanation:

C

F(13) means x equals 13.

Replace x in the equation with 13 and solve:

-13 + 3 = -10

F(13) = -10

Answer:

-10

Step-by-step explanation:

if the x in f(x) is 13, then the x in the equation is 13 and there is a negative sign in front so it is negative 13 plus 3 which is negative 10

1.How to find the longer leg of a 45 45 90 Triangle?

ans : If you know the length of one of the legs of a 45-45-90 triangle, the other leg has the same length. For this triangle, the other leg has a length of 8*sqrt(2) units. The hypotenuse's length can be found by multiplying the leg's length by sqrt(2).

Answer:

12 boys and 300 girls

Step-by-step explanation:

There are twelve more boys than girls

Answer:a) 322 MILES  B) 34.391 ( The price per gallon was not given in units ) but if price of I gallon = lets say $2.89, then for 11.5 Gallons will be $34.391

Step-by-step explanation:

a)

M r Jones car needs 28 miles for 1 gallon = 28 MILES= 1 Gallon

Number of miles he can drive withe 11.5 gallons

1 Gallon = 28 miles

11.5 gallons = 11.5 x 28miles = 322 miles

b)  IF 1 gallon costs 2.89

11.5 gallons will  cost= 11.5 x 2.89= 34.391

Step-by-step explanation:

Answer:

x > 8/15

Step-by-step explanation:

x -1/2x + 1/3 > 3/5​

Combine like terms

2/2x - 1/2x +1/3 > 3/5

1/2x   + 1/3 > 3/5

Subtract 1/3 from each side

1/2x + 1/3 -1/3 > 3/5 -1/3

1/2x  > 3/5 -1/3

Get a common denominator

1/2x > 9/15 - 5/15

1/2x > 4/15

Multiply each side by 2

2 * 1/2x > 4/15 * 2

x > 8/15

Answer:

8y=21x

Step-by-step explanation:

i'm not sure how to draw this out in a picture but the equation is above.

like the question states, Cassidy paints 8 faces in every 21 minutes. the amount of time she spends painting one face would be figured out by dividing 21 by 8 giving you 2.625minutes so i would just say around 3 minutes. so to draw a picture maybe just draw 8 faces and then circle them and say 21 minutes and then put x (to show the time she spent painting each face) under the faces in the picture and then show your work solving this.

in order to find out the ratio of time spent drawing one person's face we have to take the information given and divide the total of 21 minute span by the 8 different faces she painted in order to find how long she spends on 1 face.

hope this helps, if it did please make sure to leave a like, rate, and give me the brainliest if possible!

thanks have a great day!

Answer:

96

Step-by-step explanation:

U is the midpoint of TV, so mTU is half of mTV or mTV = 2 * mTU, so

mTV = 2 * mTU

11x + 8 = 2 (6x)

11x + 8 = 12x

8 = x

mTV = 11x + 8 = 11(8) + 8 = 88 + 8 = 96

Step-by-step explanation:

Answer:

2. 4x³ - 2x² + 4y

3. (2x+3)(2x−5)² (To expand, it would be 8x³ - 28x² - 10x + 75)

Step-by-step explanation:

2.

(4x³ + 2y) - (2x² - 2y)

Find the opposite of 2x² - 2y by finding the opposite of each term.

4x³ + 2y - 2x² + 2y

Add 2y and 2y to get 4y.

4x³ - 2x² + 4y

3.

To simplify this expression, simply multiply 2x - 5 by itself to get (2x + 3)(2x - 5)².

I know this is extra, but I'll expand it out.

(2x + 3)(2x - 5)²

Use binomial theorem (a−b)² =a²−2ab+b²  to expand (2x−5) ²

(2x + 3)(4x² - 20x + 25)

Use the distributive property to multiply 2x + 3 by 4x² - 20x + 25.

8x³ - 40x² + 50x + 12x² - 60x + 75

Combine -40x² and 12x² to get -28x².

8x³ - 28x² + 50x - 60x + 75

Combine 50x and -60x to get -10x.

8x³ - 28x² - 10x + 75

Answer:

1000 cubic feet or 1000 ft³

Step-by-step explanation:

Your friends swimming pool is in the shape of a rectangular prism, with a length of 25 feet a width of 8 feet and height of 5 feet. What is the volume of your friends swimming pool?

The volume of a rectangular prism is given as:

Width × Length × Height

Length = 25 feet

Width = 8 feet

Height = 5 feet.

Volume of the rectangular prism(Swimming pool) = 25 feet × 8 feet × 5 feet

= 1000 cubic feet or 1000 ft³
