Answer:
1.6 pizzas
Step-by-step explanation:
-2 x (4) -3 x (-5)
Hey there!
-2 x (4) -3 x (-5)
= -2(4) - 3(-5)
= -8 - (-15)
= -8 + 15
= 7
Therefore, your answer is: 7
Good luck on your assignment & enjoy your day!

Answer:
27/4
Step-by-step explanation:
because i know fractions
B.-64a^27+b^8
C.27x^9+y^6
D.81x^24+8y^40
Answer
C. 27x⁹+y⁶
Explanation
We have to test all the expressions
A.-24a^15+125b^18 = -24a¹⁵+5³b¹⁸
= -24(a⁵)³ + (5b⁶)³
-24a^15+125b^18 ⇒ Is an expression of sum of cubes.
B.-64a^27+b^8 = -4³a²⁷+b⁸
= (4a⁹)³ + b⁸
Not a sum of cubes since 8 is not divisible by 3.
C. 27x^9+y^6 = 3³x⁹+y⁶
= (3x³)³ + (y²)³
27x^9+y^6 ⇒ Is an expression of sum of cubes.
D. 81x^24+8y^40 = 81x²⁴+8y⁴⁰
= 81(x⁸)³ + 2³y⁴⁰
81x^24+8y^40 ⇒ Is an not expression of sum of cubes.
