Answer:
[tex]-3x^{2}+11x-3[/tex]
Step-by-step explanation:
[tex](-3x^{2}+6x-12)+(5x+9) = -3x^{2} + 6x - 12 + 5x + 9 = -3x^{2} + 11x - 3[/tex]
Answer:
see below
Step-by-step explanation:
Here are the simplified results of each polynomial combination.
(5x2 + 2x + 1) + (6x2 − 3x + 9)
= 5x2 + 2x + 1 + 6x2 − 3x + 9
= 5x2 + 6x2 + 2x − 3x + 1 + 9
= 11x2 − x + 10 (B)
(-3x2 + 6x − 12) + (5x + 9)
= -3x2 + 6x − 12 + 5x + 9
= -3x2 + 6x + 5x − 12 + 9
= -3x2 + 11x − 3 (A)
(8x + 16) − (3x2 − 3x − 15)
= 8x + 16 − 3x2 + 3x + 15
= -3x2 + 8x + 3x + 16 + 15
= -3x2 + 11x + 31 (D)
(5x2 + 23x − 7) − (x2 − 4x + 21)
= 5x2 + 23x − 7 − x2 + 4x − 21
= 5x2 − x2 + 23x + 4x − 7 − 21
= 4x2 + 27x − 28 (C)

Missy uses 1 hexagonal, 3 rectangular, and 4 triangular pieces of fabric to make 1 bug design for a quilt. If she uses 80 pieces in all to make bug designs, how many of each shape does she use?
Answer:10 hexagonal, 30 rectangular and 40 triangular pieces of fabrics
Step-by-step explanation:
This question is a ratio/proportion question
The ratio of hexagonal pieces use to rectangular pieces used and to triangular pieces used can be expressed as 1:3:4
Total pieces of fabrics used = 80
Total ratio = 1 + 3 + 4 = 8
We can calculate each ratio as a proportion of the total ratio
pieces of hexagonal used = (1/8) * 80 =10
Pieces of rectangular used = (3/8) * 80 =30
Pieces of triangular used = (4/8) * 80 = 40
And hence the pieces of each shapes used will be 10 hexagonal, 30 rectangular and 40 triangular pieces of fabrics
And the total number of bugs designs made = (80/8) = 10 (since it will require 8 pieces of fabrics(1 + 3 +4) to make a bug design)

Answer:
1.375 is the answer
Step-by-step explanation:
We can use the rule PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).) to solve this!
= 9+6*(1)/(7+9)-8
= 9+6*1/(7+9)-8
= 9+6*1/(16)-8
= 9+6*1/16-8
= 9+6/16-8
= 9+0.375-8
= 9.375-8
= 1.375

It takes 36 slices of pepperoni to make 4 pizzas. How many pizzas can be made using 90 slices of pepperoni?
Answer:
10.
Step-by-step explanation:
First, we take 36 and divide it by 4.
[tex]\frac{36}{4} = 9.[/tex]
Now, we take 90 divided by 9.
[tex]\frac{90}{9} = 10.[/tex]
10 pizzas can be made with 90 slices of pepperoni pizza.

Which linear equations have one solution? Check all that apply.
5x - 1 = 3(x + 11)
4(x - 2) + 4x = 8(x – 9)
4(x – 6) + 4 = 2(x - 3)
2(x – 4) = 5(x – 3) + 3
2(x - 1) + 3x = 5(x - 2) + 3
Step-by-step explanation:
linear equations have one solution are:-
5x - 1 = 3(x + 11)
4(x – 6) + 4 = 2(x - 3)
2(x – 4) = 5(x – 3) + 3

The linear equations that have one solution are:
5x - 1 = 3(x + 11)

We borrow from 5 which turns into 4 and 4 turns into 14.
14 - 5 = 9
So our first number is 9!
= __9
We borrow from the thousands, 3 becomes 2 and 0 becomes 10!
We can't subtract 4 from 9 so we borrow from 10, 10 becomes 9 and 4 becomes 14.
14 - 9 = 5
( Now i'm getting lazy so I will just show the steps without as many words )
9 - 0 = 9

054 - 095 = 959

( Borrowed from 7 to make 12 so 7 is now 6 )
12 - 4 = 8
~~~~~~~~~~~~~~~
(We need to borrow from the first 2 in 272 to make 16 from when we borrowed from 7 )
16 - 8 = 8
~~~~~~~~~~~~~~~
(2 was borrowed so it's now 1 )
1 - 1 = 0

And we get 088,959
Remove the 0 and we have 88,959
