Even number
2) 7/4×(22–x) =0
soln
= 7/4×(22 –x) =0
= 1.75 ×22 –x =0
= x=38.5
9) 15x² /7 =8x²/5
= 15x²×8x²=7×5
=120x^4 = 35
= x^4 =120–35
x^4 =85
6) 9x²/4–4=0
=9x²/4–4=0
=2.25–4=0
=4–2.25=0
=1.75
Step-by-step explanation:
use trigonometry ratios
5
that is the answer
since there are an even number of negatives, just ignore them and multiply normally. 2 x 2=4
4 x 2=8
8 x 2=16
The answer is 16
