Your answer is correct :)
Answer: -2a^3 + 9a^2 + 45a + 18b^2 + 6ab^2
Step-by-step explanation:
(a + 3) * (-2a^2 + 15a + 6b^2)
We open the brackets with (a + 3)
a ( -2a^2 + 15a + 6b^2) + 3(-2a^2 + 15a + 6b^2)
Opening the brackets
= a * -2a^2 = -2a^3
a * 15a = 15a^2
a * 6b^2 = 6ab^2
3 * -2a^2 = -6a^2
3 * 15a = 45a
3 * 6b^2 = 18b^2
Let's arrange those values weve gotten together ,don't forget the signs each carry
= -2a^3 + 15a^2 + 6ab^2 - 6a^2 + 45a + 18b^2
Collect the like terms
= -2a^3 + 15a^2 - 6a^2 + 6ab^2 + 45a + 18b^2
= -2a^3 + 9a^2 + 6ab^2 + 45a + 18b^2
Answer:
1.75(x)
Step-by-step explanation:
you can make an algebraic expression to make this simpler. if x = the number of tickets. then, you want to create the expression. it will be .... 1.75(x).
you plug whatever number you need for the table in as x. for example, if you want to see how much money diego would make for 6 tickets you write 1.75*6
Answer:
Step-by-step explanation:
The exterior angle theorem states that the exterior angle of a triangle is equal to the sum of the two opposite interior angles of the triangle.
Subtract 70 from both sides.
Sec θ = 3
1/cos θ = 3
1/sin(90 - θ) = 3
csc(90 - θ) = 3
