Question

is r = 4 a solution to this equation?
62 = 11r - r²
yes no

Explanation:

Step1: Substitute $r=4$ into equation

Substitute $r=4$ into $11r - r^2$:
$11(4) - (4)^2$

Step2: Calculate the right-hand side

$44 - 16 = 28$

Step3: Compare to left-hand side

Left-hand side is $62$, right-hand side is $28$; $62
