First you do the 4.8 + 9.9.
This equals 14.7
then you add 14.7 to the 7.5.
You get 22.2.
There is your answer!
Answer:
1. X² -2x-24= 0
2. X² -3x+2= 0
3. 2x² -7x -8= 0
4. 3x² + 38x +24= 0
Step-by-step explanation:
1.(-4,6)
(X+4)(x-6)= 0
X² -6x + 4x -24= 0
X² -2x-24=0
2.(1,2)
(X-1)(x-2)=0
X²-2x-x+2=0
X²-3x+2=0
3.(8,-1/2)
(X-8)(x+1/2)=0
X² +1/2x -8x -4=0
X² -7/2x -4=0
2x² -7x -8=0
4.(-2/3,-12)
(X+2/3)(x+12)=0
X² + 12x +2/3x + 8=0
3x² + 38x +24=0

Answer:
Step-by-step explanation:
√24 = 2√6
√48 = 4√3
Then the sum is ...
√24 +√48 = 2√6 +4√3
Factoring out √3, we have ...
= (2√2 +4)√3
Matching this to the form a√b, we have
(2√2+4)√3 ⇒ a=2√2+4, b = 3
