Answer:
12sweet
Alex's ratio=3
Thomas' ratio =2
I.e 3+2=5
Sweet=30
Thomas' share=2/5*30
=12
I.e Thomas' share is equal to 12 sweets
Answer:
k = 3.
Step-by-step explanation:
By the Factor Theorem. if x+a is a factor of f(x) then f(-a) = 0.
Here we use f(-1):
f(-1) = (-1)^3 + 2(-1) + k = 0
-1 - 2 + k = 0
k = 3.
4. Here you would use the Pythagorean Theorem. a² + b² = c²
In this case a and b are the same, so : a² + a² = c² would also work.
a = 5√2 so: (5√2)² + (5√2)² = c²
Do you know where to go from here?
Ok, this is what you do,
7(^^^^^
84
7 goes into 8 1 time so it would be this
1
7(^^^^
84
- 7
and it leaves you with 14
1
7(^^^^
14
then how many time does 7 go into 14? 2 times
so it would be
12
7(^^^^
14
-14
AND YOUR ANSWER IS 12.
Ans: x=1.590667 or x= -1.257334
