Answer:
y = x^2 +6x+14
Step-by-step explanation:
x = t - 3, y = t^2 + 5
x=t-3
Add 3 to each side
x+3 = t-3+3
x+3 =t
Substitute into the second equation
y = t^2 +5
y = (x+3)^2 +5
Foil the first term
y = (x+3) (x+3) +5
y = (x^2 +3x+3x+9) +5
y = x^2 +6x+9) +5
y = x^2 +6x+14
Answer:
x= -33/2 or x=-16.5
Step-by-step explanation:
Expand the bracket
6(2x+3) = 2(5x-3)
12x+18=10x-15
Bring like terms together
12x-10x=-15-18
2x=-33
x=-33/2
614.40 because 204.80 divided by 4 is 51.20 and 51.20 multiplied by 12 is 614.40
Area of square is a^2
4^2 = 16
the area is 16 units
