Answer:
44, 46
Step-by-step explanation:
The integers are both even, so if the smaller one is x, then the larger one is x+2.
Therefore:
((x) + (x+2))² = 4048 + (x)² + (x+2)²
(2x + 2)² = 4048 + x² + x² + 4x + 4
4x² + 8x + 4 = 2x² + 4x + 4052
2x² + 4x - 4048 = 0
x² + 2x - 2024 = 0
(x + 46) (x - 44) = 0
x = -4+, 44
Since x must be positive, x = 44. And x+2 = 46. So the numbers are 44 and 46.
Let's check:
(44 + 46)² = 8100
4048 + 44² + 46² = 8100
Answer:
A)
B) 240 pages
Step-by-step explanation:
From the table, he can read 20 pages in 6 minutes and 15 paged in 50 minutes.
The unit rate can be found using
Using the point (6,20) and the unit rate we can find the equation using
B) When x=72 minutes we substitute
Answer:
(-3,2)
Step-by-step explanation:
About 96, as it's 50 x 3 for 150 people, so you do 32 x 3 to get 96.
