Where a= next number in the sequence:
a=n(-3) + 6
Answer:
5
Step-by-step explanation:
Since the difference in each term number is 5, we put 5 in the place of the star.
Formula for constant difference in a pattern: Tn= an+b
a is the difference while b is the number that comes before the 1st term. So, the equation to find the nth term is Tn=5n+4.
Hope this helps and please give a brainlist, thank you!
X+8y=18
-5x+3y=-4
Multiply the first equation by 5
Add the two equations together
5x+40y=90
-5x+3y=-4
43y=86
Y=2
Plug y into one equation to find x
X+16=18
X=2
Answer:
202.5cm^2
Step-by-step explanation:
P=2l+2w
63=2(9)+2w
63=18+2w
63-18=2w
45=2w
divide both sides by 2
22.5=w
check:
P=2(9)+2(22.5)
=18+45
=63
Area=l×w
=22.5×9
=202.5cm²
