Answer:
8x^2-4x+5
Step-by-step explanation:
(3x^2+4)-(-5x^2+4x-1)
Let's start by removing the parentheses.
3x^2+4-(-5x^2)-4x+1
Now let's reorder the equation to make it easier to combine like terms.
3x^2+5x^2-4x+1+4
Combine like terms.
8x^2-4x+5
Abigail would be 32 and Cynthia would be 24 now. Twenty years ago, Abigail was 12, and Cynthia was 4. 12 is 3 times as much as 4, and also 4+8=12.
Answer:
x=3
Step-by-step explanation:
2(x+1)=x+5
Use the distributive property to multiply 2 by x+1.
2x+2=x+5
Subtract x from both sides.
2x+2−x=5
Combine 2x and −x to get x.
x+2=5
Subtract 2 from both sides.
x=5−2
Subtract 2 from 5 to get 3.
x=3
