Rewrite in simplest terms: (3x + 2) + (-10x – 3)

Mathematics
1 answer:
Andre45 [30]3 years ago
8 0

Answer:

\boxed {\tt -7x-1}

Step-by-step explanation:

We are given the expression:

(3x+2)+(-10x-3)

Combine like terms.

The terms with variables can be combined, then the terms without variables (constants) can be combined.

(3x+-10x)+(2+-3)

(3x-10x)+(2-3)

Subtract 10x from 3x.

(-7x)+(2-3)

Subtract 3 from 2.

(-7x)+(-1)

-7x-1

The simplified expression is -7x-1

1. A tree 5 ft tall grows an average of 8 in. each year. Which equation models the trees height h after x years?
slega [8]
Well we know that it grows 8 in a year. so after 1 year has grown 1 * 8 and after 2 years 2 * 8 and after 3 years 3 * 8 and so on. since x is the year we can say 8x. but it starts with 5 ft so we add in the 5 to get h.
h = 8x + 5

A manufacturer makes two type if products X and z at each if two different locations A and B. the materials used to make each if
Snezhnost [94]

Using matrix algebra, the material cost of making one of each product at each location is as follows:​

<h3 />

                       Product X    Product Z

Location A        birr 38          birr 50

Location B        birr 38          birr 49.5

<h3>What is matrix algebra?</h3>

Matrix algebra involves the arrangement of numbers in a rectangular array.

Matrices are arranged in columns and rows to express some mathematical values.

<h3>Data and Calculations:</h3><h3>Matrix O: Materials Requirement Per Unit</h3>

                      Steel    Glass    Plastic

Product X         3            1             2

Product Z         4          0.5           3

<h3>Matrix P: Materials Cost Per Unit</h3>

                      Steel    Glass    Plastic

Location A      10           2           3

Location B       9           3           4

<h3>Matrix R: (O x P) Material Cost of Product X</h3>

                      Steel    Glass    Plastic   Total

Location A     30           2           6          38

Location B     27           3           8          38

<h3>Matrix R: (O x P) Material Cost of Product Z</h3>

                      Steel    Glass    Plastic   Total

Location A     40          1             9          50

Location B     36          1.5         12         49.5

Thus, Product X costs birr 38 at locations A and B, respectively, while Product Z costs birr 50 and birr 49.5 at locations A and B, respectively.

Please help for solve this question
Schach [20]
You set up the problem correctly, just keep going.

Expand out your expression:

2x(3x-9) + 4x(x+13)
= 6x^2 -18x + 4x^2 + 52x 
= 10x^2 +34x

Remember that the above expression is the area, so it is equal to 24.

10x^2 + 34x = 24
10x^2 + 34x - 24 = 0     (divide by 2)
5x^2 + 17x - 12 = 0

Done.
