24a ^ 2-6a-9.
you should do in this case is to see the terms that are repeated in the expression.
WE have then that the terms are a and the multiples of 3.
Making a common factor we have:
24a ^ 2-6a-9.
3 (8a ^ 2-2a-3).
3 (a (8a-2) -3)
Answer:
The equivalent expression is:3 (a (8a-2) -3)
Answer:
the amount that need to be paid by her is $633.60
Step-by-step explanation:
The computation of the amount that need to be paid by her is shown below:
= Purchase value of merchandise - purchase value fo merchandise × discount rate
= $720 - $720 × 12%
= $720 - $86.4
= $633.60
hence, the amount that need to be paid by her is $633.60
Answer:
Therefore either a:b = 5:4 or a:b=-5:4
Step-by-step explanation:
ax²-5bx+4a=0
Since the quadratic equation has two real root.
Then b²-4ac>0
Here a= a , b= -5b and c=4a
∴(-5b)²-4.a.4a=0
⇔25b²=16a²
⇔5b=±4a
Therefore either a:b = 5:4 or a:b=-5:4
Answer:
number 3. is wrong you can reduce once more and it will equal 3/5. and number 4 would be 5/7.
Step-by-step explanation:
divide 12/20 by 2 on the top and bottom. you should get 6/10. you can divide that once more by 2 on the top and bottom and you should get 3/5. thats simplest form.
divide 25/35 by 5 on the top and bottom youll get 5/7. thats the simplest form.
hope this helped :)
Hi there!
To find the area of the kite, we find the area of both triangles and add them up.
8.5 + 8.5 = 17
17 × 4.93 = 73.81
73.81 ÷ 2 = 36.905
17 × 10.2 = 173.4
173.4 ÷ 2 = 86.7
36.905 + 86.7 = 126.805
The area is the kite is 126.805 m squared.
Hope this helps!
