Mathematics
1 answer:
miskamm [114]3 years ago
6 0

Step-by-step explanation:

_______________________________________

2 {x}^{2}  + x - 3

Write the equation

_______________________________________

= 2 {x}^{2}  + 3x - 2x - 3

expand x into 3x and -2x

_______________________________________

= x(2x + 3) - (2x + 3)

take x out and 2x+3 in bracket and take - out and 2x+3 in brackets

_______________________________________

= (2x + 3)(x - 1)

This is something about absolute value but i have no idea how to do it
Advocard [28]

You're looking for an inequality of the form |t-b|\le a, or -a\le t-b\le a, or b-a\le t\le b+a.

Start with

350^\circ\le t\le400^\circ

Notice that 375º is the midpoint of this interval of temperatures. If we subtract all sides by 375º, then we get

-25^\circ\le t-375^\circ\le25^\circ

so we can set a=25^\circ and b=375^\circ, and we can rewrite this inequality in terms of absolute values as

|t-375^\circ|\le25^\circ

This diagram shows the dimensions of a plastic tab
Aleksandr-060686 [28]

Answer:

2340 mm

Step-by-step explanation:

We know that since the rectangular prism has a square base, the length and width are equal

So we have V = 10 * 10 * 15

For the small rectangular slab we can subtract 10 from 40 to get 30 for the length

Thus we have V = 30 * 4 * 7

Hope this helps
