Ok so for number 5, AB is proportional to BC just like PQ is proportional to QR. AB = 9, BC = 15, PQ = 3, and QR = x. 9/15 = 3/x. Cross Multiply: This gives you - 9x = 45. Divide both sides by 9, and you get x = 5. QR = 5
I can’t see it but if I had to say it would be D.
Answer:
20/3 - 59/15 = 41/15
6 2/3 - 3 14/15 = 2 and 11/15
Step-by-step explanation:
Answer:
a= 
Step-by-step explanation:
to find a isolate it on one side by taking 1/3 by subtraction to the other side
a= 
- 
=
x^2+7x+12 can be done by factoring as a process of ax^2+bx+c, whereas a is equal to 1.
First, we need to know 2 numbers that multiply to 12 and add to 7. In that case, that would be 6 and 2. And then finally write the variable x in the first parts of the parentheses, that would be: (x+6)(x+2).
