Step-by-step explanation:
4.5x-2.3=6.7 (add 2.3 so no number in the equation)
6.7+2.3 is 9
4.5x=9 (divide by 4.5 as it's 9 is divisible by 4.5
9/4.5 is 2
X=2
put it back into the equation
4.5*2 is 9
9-2.3 is 6.7
Therefore X=2
Answer:
Step-by-step explanation:
(a + b)² = a² + 2ab + b²
(x + 1)² = x² +2*x*1 + 1² = x² + 2x + 1
y = 4(x+1)² - 4
y = 4(x² + 2x + 1) - 4
y = 4*x² + 4*2x + 4*1 -4
y = 4x² + 8x + 4 - 4
y = 4x² + 8x
