OH right! I should have realised that!
S6 = 7,812 = a1 * (5^6 - 1)
----------- were a1 = first term
5 - 1
3906*a1 = 7812
a1 = 7812 / 3906 = 2
Therfore the second term = 2*5 = 10 Answer
Answer:
915
Step-by-step explanation:
V=l*w*h V=1/2*b*h*l
V of the rectangular block: 15*5*8 = 600
V of the triangular prism--it's easiest to solve half of it, then just multiply that answer by 2: 1/2*5*7*9 = 157.5
When you double it, it cancels out the 1/2
157.5*2=315
315+600=915
The correct answer is b hope this helped u
When using the distributive law
answer is: 45x-27
Answer:
a) 5
Step-by-step explanation:
Put them into slope intercept form AKA y=mx+b: -5=m1+b <em>and</em> 5=m3+b
Subtract the equations to get -10=-2m
Divide both sides by two to get: 5=m
Hope this helps! (^-^)
