Answer 1

Answer:

are we supposed to solve this???

Answer 2

Answer:

18x^5y^4+27y^8−8x^7−12x^2y^4

Step-by-step explanation:

(2x^5+3y^4)(−4x^2+9y^4)

=(2x^5+3y^4)(−4x^2+9y^4)

=(2x^5)(−4x^2)+(2x^5)(9y^4)+(3y^4)(−4x^2)+(3y^4)(9y^4)

=−8x^7+18x^5y^4−12x^2y^4+27y^8

=18x^5y^4+27y^8−8x^7−12x^2y^4

Answer:

-4.75

Step-by-step explanation:

We're trying to find the number that's between -4 and -5. B is on -4.5, so we need to find a number between -4.5 and -5. This would be -4.75. Think of it like quarters, 4 quarters equal a dollar, and B would be the 2nd quarter (which is 50 cents). D would be the 3rd quarter (which is 75 cents). That's where the ".75" comes into the answer "-4.75". Just remember to put NEGATIVE 4.75 and NOT positive 4.75 since this is a negative number.

y is an irrational number between 3 and 4 . what is the value of y

Answers

Answer:

If a and b are two positive rational numbers such that ab is not a perfect square of a rational number, then ab is an irrational number lying between a and b.

So  an irrational number between 3 and 4 is=3×4=3×4=3×2=23


What are the values of a and b, and what is an equation for the line?

Answers

Answer:

a = 1,  b = 6

Step-by-step explanation:

slope of line = (5-2) / (12-3) = 3/9 = 1/3

(3-2) / (b-3) = 1/3

b-3 = 3        b = 6

(2-a) / (3-0) = 1/3

2-a = 1          a = 1

A vendor bought 80 pineapples ₱18.50 each. Three pineapples got rotten, but then he sold the rest at ₱25.00 each. how much did he gain?​

Answers

Answer:

₱445

Step-by-step explanation:

₱18.50(x)

x = number of pineapples purchased

₱18.50(80) = ₱1480

80 - 3 = 77

₱25.00(z)

z = number of pineapples resold.

25.00(77) = ₱1925

₱1925 = ₱1480 = ₱445
