answer for sir is 27 and second is -18
Ok, make sure you put the powers correctly. I know what you mean but someone else may not. So it's step 2. This is because the 4 doesn't mean add a digit.
Cross-multiply:
7 * 3 = 5 * x
Divide each side by 5 :
X = 7 * 3 / 5 = 4.2
C=2
r
A=
r<span>²
C=2</span>
r=58
2r=58
r=29
A=
r<span>²
A=29</span><span>²</span>
A=841
Let's cut the chit chat, and formalities. I'm not one for greetings or unnecessary niceties.
Divide 0.5 by 10=
0.05
Check work.
0.05 x 10 = 0.5
