Question

ANSWERR..VERY URGENT

Answer 1

Answer:

(1) 10 (2) -1.6

Step-by-step explanation:

(1) Here, m = 2 and n = -1

so, 2m² + n² +1

= 2(2)² + (-1)² + 1

=2 (4) + (1) +1

= 8 + 1 + 1

= 10

(2) Here, a = 4

so, 3a/5 - 4

= 3(4) / 5 - 4

= 12/5 - 4

= 1.6

Hope it helps :)

Answer 2

1. Here,

m = 2

n = -1

2m²+n²+1

= 2×2²+(-1)²+1

= 2×4 +1+1

= 8+1+1= 10

2. a= 4

3a/5 - 4

= 3×4/5 - 4 ( a=4)

= (12 - 20)/5

= (3×4 - 20)/5

=(12 - 20)/ 5

= -8/5
