We have to add the amounts:
4(2x+3y) + 3(5x+4)
First, though, we have to distribute:
4*2x + 4*3y + 3*5x + 3*4
8x + 12y + 15x + 12
Now we just need to simplify:
23x + 12y + 12
The students planted 23x + 12y + 12 trees total.
Answer:
$11.5
Step-by-step explanation:
Add all of them together
An absolute value of any number cannot result in a negative number.
There are no possible points where |x| can equal -5.
Answer:
13ab
Step-by-step explanation:
When you add the 5 and 9 it will give you 14 but you still have to subtract the 1ab(there is a 1 in front of variables that don't have a visible number.) So it will be 13 a b.
Step-by-step explanation:
in ∆ABC and ∆ADC
AB = AD (given)
AC = AC (common)
angle ACB = angle ACD = 90° (Given)
therefore,
∆ABC = ∆ADC
therefore, option C is correct
hope this helps you!
