1. (5x² - 6x +2)+(9x + 10x - 7) - what is the answer?

Mathematics
1 answer:
yanalaym [24]3 years ago
6 0

Answer:

Step-by-step explanation:

the way it is written, the answer is

5x^2 - 6x + 2 + 19x - 7

5x^2 + 13x - 5    is the answer.

However I suspect you mean

5x^2 - 6x + 2 + 9x^2 + 10x - 7

14x^2 + 3x - 5    is the answer if the revision I've made is correct.

Each of the 6 cats in a pet store was weighed. Here are their weights
zhannawk [14.2K]

Answer:

Mean= 10.83

Median= 9.5

Step-by-step explanation:

Given number,

10, 15, 8, 11, 9, 12

N= 6

As we know,

Mean= Ex/N

=10+15+8+11+9+12/6

=65/6

=10.83

Therefore, Mean= 10.83

Now,

Median(MD)= (N+1/2)th item

= 6+1/2

=7/2

=3.5th item

So, Median(MD)= 3th+4th/2 item

= 8+11/2

= 19/2

= 9.5

Therefore, Median= 9.5

Find the indicated maximum or minimum value of f subject to the given constraint. maximum: f(x,y,z)=x2y2z2; x2 y2 z2=4
Ksju [112]

The indicated maximum or minimum value of f is subject to the given constraint maximum is 125/27.

An instance of a constraint is the fact that there are only such a lot of hours in a day to perform things. Embarrassed reserve or reticence; awkwardness. One that restricts, limits, or regulates; a take a look at.

A constraint is something that limits or controls what you can do. Their decision to abandon the trip was made due to monetary constraints. Water shortages in the location can be the primary constraint on development.  Synonyms: restriction, issue, lessen, rein greater Synonyms of constraint.

Constraints are used to limit the kind of records which can move right into a desk. This guarantees the accuracy and reliability of the facts inside the table. If there's any violation between the constraint and the facts motion, the motion is aborted. Constraints can be column stage or desk level.

George decided to use blue paint to paint a wall with two windows. The wall is 12 7 8 ft by 8 ft. Both windows are 3 1 2 ft by 4
masha68 [24]

Answer:

71 1/2 square feet

Step-by-step explanation:

We want to find the area of the wall that will be painted.

We need to find the area of the two windows and subtract it from the area of the wall.

Each window is 3 1 /2 ft by 4 1/2 ft. The area of each window is therefore:

A = L * B

A = 7/2 * 9/2 =  = 63/4 square feet = 15 3/4 square feet

The two windows therefore have an area of:

2 * 63/4 = 63/2 = 31 1/2 square feet.

The wall measures 12 7/8 ft by 8 ft. Therefore, the area of the wall is:

A = 103/8 * 8 = 103 square feet

The area of the wall that will be painted is therefore:

A = 103 - 31 1/2 = 71 1/2 square feet
