Answer:
Neither.
Step-by-step explanation:
The gradients to the line are not co-related.
Answer:
Matt should have factored out the leading coefficient 2 on the second step before completing the square
Step-by-step explanation:
To complete the square, you must first factor the leading coefficient from the first two terms.
y = 2x² − 10x − 4
y = 2 (x² − 5x) − 4
y = 2 (x² − 5x + 25/4 − 25/4) − 4
y = 2 (x² − 5x + 25/4) − 25/2 − 4
y = 2 (x − 5/2)² − 33/4
Answer:
214.2 units²
Step-by-step explanation:
To find the surface area, we add the area of all the 6 sides.
2(Length x Width) + 2(Length + Width) x height
Surface area
= 2(6.5 x 8) + 2(6.5 + 8) (3.8)
= 104 + 110.2
= 214.2 units²
