Question

Q4.Find the value of expression 5y² - 4z for y = 3 and z = 2 ​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

The value for the expression $5y^{2} -4z$ for $y=3$ and $z=2$ is 37

Step-by-step explanation:

Given

$5y^{2} -4z$

When $y=3$ and $z=2$,

$5y^{2} -4z=(5*3^{2} )-4*2\\\\=(5*9)-(8)\\\\=45-8\\\\=37$

So the value for the expression $5y^{2} -4z$ ehen$y=3$ and $z=2$ is 37
