Answer:
upward
Step-by-step explanation:
y=4x²+4
Look at the coefficient of x²
If it is positive, it opens upward, IF it is negative, it opens downward.
In this case, the x² coefficient is +4, hence it opens upward
(see attached for plot)
4:1 is the answer............
Answer:
it will be $80.00 and your saving $20.00
Step-by-step explanation:
We know that the shorter side of the rectangle is 1/2 of the longer side (because it's a square folded in half). To meet this condition and to have a perimeter of 24cm, we may assume that the dimension of the rectangle are 8cm x 4cm.
Now if we unfold it, we'll get a square of 8cm x 8cm. To find the are we just need to find 8², which is <u>64 cm²</u>.
