Mathematics

Sholpan [36]3 years ago
4 0

Answer:

Infinitely many.

Step-by-step explanation:

3x + 2y = 4

-6x - 4y = -8

Note that the second equation is obtained from the first by multiplying the first one by -2. Thus the graph of the 2 equations is the same line and there are infinitely many solutions.

What is the product if a-3 and -2a^2+15a+6b2
Ierofanga [76]

The product if a-3 and -2a^2+15a+6b^2 is: -2a^3+21a^2+6ab^2-45a-18b^2

Step-by-step explanation:

In order to find the product of 2 expressions, distributive property can be used.

Given expressions are:

a-3\\and\\-2a^2+15a+6b^2

Product of given expressions

= (a-3)(-2a^2+15a+6b^2)\\= a(-2a^2+15a+6b^2)-3(-2a^2+15a+6b^2)\\= -2a^3+15a^2+6ab^2+6a^2-45a-18b^2

Combining like terms

= -2a^3+15a^2+6a^2+6ab^2-45a-18b^2\\=-2a^3+21a^2+6ab^2-45a-18b^2

Hence,

The product if a-3 and -2a^2+15a+6b^2 is: -2a^3+21a^2+6ab^2-45a-18b^2
