VikaD [51]

Answer:

<h3>The answer after performing the indicated operation is in descending powers of x is 5x^2-7x+15</h3>

Step-by-step explanation:

Given expression is (6x^2-4x+11)+(4-x^2-3x)

<h3>To perform the operation indicated, then place the answer in the proper location on the grid and also Write answer in descending powers of x:</h3>

Now solve the given expression as below ( that is perform the operation indicated)

(6x^2-4x+11)+(4-x^2-3x)

=6x^2-4x+11+4-x^2-3x

Adding the like terms we get

=5x^2-7x+15

(6x^2-4x+11)+(4-x^2-3x)=5x^2-7x+15

<h3>The answer after performing the indicated operation is in descending powers of x is 5x^2-7x+15</h3>

Consider two circular swimming pools. Pool A has a radius of 22 feet, and Pool B has a diameter of 13.6 meters. Complete the des
Black_prince [1.1K]

Answer:

See below.

Step-by-step explanation:

Diameter of pool A = 2 * radius = 2 * 22

= 44 feet

= 44 * 0.305 = 13.42 meters.

The diameter of Pool B ( 13. 6 m)  is greater than the diameter of Pool A.

The circumference of Pool A is 13.42 * pi = 42.16 m and that of B is 42.73 m, so that  the circumference of Pool B is greater than that of Pool A by

0.57 m.

1.The length of a ship model is 3% of the length of the actual ship. The model is 1.5 M long. How long is the actual ship? ____M
Vilka [71]
We have to find 100% of the number. We can use proportion to get it
3% -----------1.5m
100% -------- x
crossmultiply now
3*x=1.5*100
3x=150      /:3 divide both sides by 3
x=50m

2. Similar situation
40% ------------1000
100% -----------x
crossmultiply
40*x=100*1000
40x=100000      /:40
x=2500 - its the answer
