c. 13
d.-1​

Answer 1

Answer:

A3+b3+c3

=-8+1+8

=1 is your right answers

Answer 2

Answer:

$\huge\bigstar\underbrace{\mathtt\red{A} \mathtt\purple{N} \mathtt\green{S}\mathtt\blue{W} \mathtt\blue{E} \mathtt\orange{R}}\bigstar$

Step-by-step explanation:

$\huge\sf{\pink{\fbox{\blue{\fbox{\purple{\fbox{\pink{Given:}}}}}}}}$

$\bigstar$ a= -2

$\bigstar$ b= 1

$\bigstar$ c= 2

$\huge\sf{\pink{\fbox{\blue{\fbox{\purple{\fbox{\pink{To\:Find:}}}}}}}}$

$(a^3+b^3+c^3)$

$\huge\sf{\pink{\fbox{\blue{\fbox{\purple{\fbox{\pink{Solution:}}}}}}}}$

$a^3= (-2)^3= -8$

b^3= (1)^3= 1

c^3= (2)^3= 8

$\huge\sf{\pink{\fbox{\blue{\fbox{\purple{\fbox{\pink{Substituting\:values}}}}}}}}$

$-8+1+8 = 1$
