Answer:

x^2 + 2x = 3x+20

-3x

x^2 - 1x = 20

- 20

x^2 -1x -20=0

(x-5)(x+4)

x-5 =0 or x+4=0

x = 5 or x= -4

Sajia has 30 Books in her library. she sold 9 books at the thrift store on Saturday. Write and solve and inequality to determine

ELEN [110]

Sajia can sell 21 books she can sell if she comes back on sunday and the required inequality is $9 + x \leq 30$

Solution:

Given that Sajia has 30 Books in her library

She sold 9 books at the thrift store on Saturday

To find: We have to write and solve an inequality to determine number of more books she can sell if she comes back on sunday

Let "x" be the number of more books she can sell if she comes back on sunday

We can write a inequality as:

$\text{ books already sold } + \text{ number of books remaining } \leq \text{ total number of books she has }$

$9 + x \leq 30$

Now moving 9 from L.H.S to R.H.S we get,

$x \leq 30 - 9$

On solving 30 - 9 = 21,

$x \leq 21$

So Sajia can sell 21 books she can sell if she comes back on sunday

Aziza has a triangle with two sides measuring 11 in. and 15 in. She claims that the third side can be any length as long as it i

irina [24]

Answer:

Aziza’s claim is incomplete. The third side must be between 4 in. and 26 in.

Step-by-step explanation:

With the Triangle Inequality Theorem, saying that the sum of lengths of any two sides of a triangle is greater than the length of the third side. With this we can develop two inequalities:

11 + 15 > x

26 > x

rewrite this as x < 26

11 + x > 15

x > 15 - 11 Subtract 11 from both sides

x > 4

Therefore, the third side can be anywhere greater than 4 inches and less than and less than 26 inches.

4 < x < 26
