Answer:
4b^4 + 6b^3 + 13b^2 + 10b -1
Step-by-step explanation:
4b^4 + 12b^3 + 5b^2 + 6 - (6b^3 – 8b^2 – 10b + 7)
= 4b^4 + 12b^3 + 5b^2 + 6 - 6b^3 + 8b^2 + 10b - 7
= 4b^4 + ( 12b^3 - 6b^3) + (5b^2 + 8b^2) + 10b + (6 - 7)
= 4b^4 + 6b^3 + 13b^2 + 10b -1
Answer:
The anwer is A
Step-by-step explanation:
If it is a right angle triangle we use paythagoras theorem
a ×a + b× b= c × c
- so we use the side which is straight to the 90° angle for the variable C. For variable A and B it doesn't matter we can use what we want.
- so the side which is straight to the 90° angle is 17.
- now let's substitute
1. 15× 15( square of 15) + b× b(square of b) = 17 ×17 (square of 17)
;2. 225 + b×b(square of b ) = 289
3. b×b(square of b) = 289-225
4. b × b( square of b )= 64
b = 8

Answer:
Hi there!
Your answer is:
f(-4) = 24
Step-by-step explanation:
F(-4) means to plug in -4 for x!
-4(-4) +8
16+8= 24
f(-4) = 24
