Answer:
5.3624785e+55
Step-by-step explanation:
Answer:
- 896
Step-by-step explanation:
To find the 8 th term substitute n = 8 into the explicit formula
= 7 × = 7 × - 128 = - 896
Answer:
the answer is 12
Step-by-step explanation:
p(n)= 6-2(1+n)
so if p(2)
then n=2
therefore,
p(2)= 6-2(1+2)
= 4×3
=12
Hey there!
Formula for the area of a triangle is (1/2)bh.
Base of this triangle is 5, height is 4.
Image attached.
Plug values into the formula:
A = (1/2)(5)(4)
Simplify.
A = (1/2)(20)
A = 10
Area of the triangle is 10 units².
Hope this helps!
You can start by multiplying the first equation by twelve, by doing this you get whole numbers. This yields:
4x + 3y =12
2x - 3y = -30
As you can see, you have two terms that only differ in sign.
By adding both equations together you get this:
6x=-18 or x=-3
The reason why you can add these equations together is illustrated in the next example:
4=x
5=y
4+5=x+y
Simple no?
Now that you now x you can substitute the value in one of the equations and you get the y value:
4*-3 + 3y =12
-12 + 3y =12
3y= 24
y=8
