(x+3)(5x+4)
Answer:
2x^2 + 3x + 2
Step-by-step explanation:
Like terms must have exactly the same variables and exponents on the variables.
2x^2 is not a like term to any other term, so it cannot be combined.
3x is not a like term to any other term, so it cannot be combined.
3 and -1 have no variable, so they are like terms and can be combined.
2x^2 + 3 + 3x - 1 =
= 2x^2 + 3x + 3 - 1
= 2x^2 + 3x + 2
Answer: $61.50
Step-by-step explanation:
To do this you need to first find 18% of 75 which is 13.5 or $13.50 and then subtract that from the original price being $75 and you get $61.50
HOPE THIS HELPS ^^
Answer:
x=1/3 or x=−3/2
Step-by-step explanation:
7x2+10x−3=x2+3x
Step 1: Subtract x^2+3x from both sides.
7x2+10x−3−(x2+3x)=x2+3x−(x2+3x)
6x2+7x−3=0
Step 2: (3x−1)(2x+3)=0
Step 3: Set factors equal to 0.
3x−1=0 or 2x+3=0
x=1/3 or x= −3/2
Answer:
y = 10
Step-by-step explanation:
Given
10 - y = y - 10 ( subtract y from both sides )
10 - 2y = - 10 ( subtract 10 from both sides )
- 2y = - 20 ( divide both sides by - 2 )
y = 10
