Answer:
day 540
Step-by-step explanation:
He increases his number of situps by 2 each day meaning on day 1 he'd do 2 extra, on day 2 he'd do 4 extra, on day he'd do 6 extra etc. We can show this by saying +2x where x is the day he is on. Then since he started with 20 we have to add 20 so it would be 20+2x. We want to know what day it is when he does 1100 situps so we can set our equation equal to 1100 and solve for X which is the day it would be.
20+2x=1100
2x=1080
I hope this helps and please don't hesitate to ask if there is anything still unclear!
x=540
Answer:
Not a right triangle.
Step-by-step explanation:
We can tell if it's a right triangle or not by using the Pythagorean Theorem.
The largest value is always the hypotenuse (c).
a² + b² = c²
24² + 70² = 75²
576 + 4900 = 5625
5476 ≠ 5625
The values do not equal one another. Therefore, this triangle is NOT a right triangle.
The GCF is of 11ab +32ab is 43ab
X^2 + 6x + 9
x 3
x 3
(x+3) (x+3)
x^2 + 3x + 3x + 9 (FOIL method)
x^2 + 6x + 9 (true)
your answer is 9 as the constant
hope this helps
