9x^2(2x^2 + 3x -4) / 9x^2
= 2x^2 + 3x -4
The answer is A. Hope this helps!
Answer:
8.−2x^2+6x
9.y-1
Step-by-step explanation:
8.(−2x)(x−3)
=(−2x)(x+−3)
=(−2x)(x)+(−2x)(−3)
=−2x^2+6x
9. y^2−y
y
= y^2−y
y
=y−1
Let's figure out how many square yards you have by first converting all of the measurements into yards:
30 inches x( 1 yard/36 inches) = 30/36 yd = 5/6 yd
12 feet x (1 yard/3 feet) = 4 yards.
Now multiply length x width:
5/6 x 4 = 20/6 or 3 1/3 square yards.
Finally, multiply unit price by square yards:
$6 per sq yd x 3 1/3 sq yd = $20 cost
Answer:
Noah's claim is correct
Step-by-step explanation:
B O D M A S - Brackets, Over, Division, Multiplication, Addition and Subtraction, this means that you must do the addition first.
2x+ 4x = 6x
9x - 6x = 3x
Noah is correct as the - sign tells us that you have to subtract everything after the 9x
Hope this is ok and helps a little bit
Alright, so in order to find this, you will nee to use the Triangle Inequality Theorem.
We’ll make the values = to variables to make it easier. a=1 b=1 c=2
All of the inequities need to be true.
a+b>c
b+c>a
c+a>b
Now replace the variables.
1+1>2 2>2 (False)
1+2>1 3>1 (True)
1+2>1 3>1 (True)
Since one is false, 1,1, and 2 cannot make a triangle.
