That is about coordinates and the dot product
we have a has coordinates (4;8)
and b has coordinates (-2;3)
So we have a.b= 4x(-2)+ 8x3= -8+24=16
The answer is 16
Answer:
113
Step-by-step explanation:
To find the result of the equation, you just have to apply the given information that x = 3 and y = -5 into the equation:
31x + y2 - (xy)2
= 31 * 3 + -5 * 2 - (3*-5) * 2
= 93 + -10 + 15 * 2
= 93 -10 + 30
= 83 + 30
= 113
Hope this help you :3
