Answer:
C=1 ft
Step-by-step explanation:
c2= a2 + b2 - 2ab
= 8^(2) + 7^(2) - 2(8)(7)
= 113 -112
c2= 1 put a square root on c2 and 1
c = 1
hello!
so the answer that you put there is actually wrong and i'll tell you why and how to do it
so since you are adding the two:
-8x + 9x = x (so you got this part right)
-12 + 4 = -8 (this is where you got it wrong, -12 added 4 goes up in value to -8)
so the final answer is x - 8
i hope this helped and have a nice day!
Answer (it has two solutions):
- x = 4
- x = -6
I hope this helps!
6.08x10^-12
This means that we move the decimal to the left 12 times. Which is .00000000000608
85p + 97p + 58p = £2.64
£2.40 - £5 = £2.60
