(88 + 94 + 89 + 85 + x) / 5 = 90
(356 + x) / 5 = 90
356 + x = 90 * 5
356 + x = 450
x = 450 - 356
x = 94 <==

4 out of 30= 7.5
Both numbers, 14 and 4, have the same ratio.
it should be squared by x. it would then read. y=4 (2)^×
5x²+13x-4-17x²-7x+19+15x²+5x-21x-7=
=5x²+15x²-17x² +(13x-7x+5x-21x) -4-7+19=
=3x²-10x+8
