Question

If 3x + 4y = 16 and xy = 2 find 9x² +16y
on 16y on y square will be there ​

Answer 1

Answer:

184

Step-by-step explanation:

given

3x+4y=16

$(x + y)square = x2 + 2(x)(y) + y2$

(3x+4y)²=(16)²

9x+36xy+16y=256

(9x²+16y²) +36xy=256

(9x²+16y²) +36(2) =256

9x²+16y²+72=256

9x²+16y²=256–72=184
