Step-by-step explanation:
i hope this makes sense lol. You can see it's a linear since it decrease at a steady rate. so you have to find the slope and find the y- intercept
Answer:
The coefficient of the 2nd term of trinomial is 18.
Step-by-step explanation:
You can expand in a faster way by using the formula, (a+b)² = a²+2ab+b² :
(3x+3)² = (3x)² + 2(3x)(3) + 3²
= 9a² + 18a + 9
OR
You can expand it by doing step by step :
(3x+3)² = (3x+3)(3x+3)
= 3x(3x) + 3x(3) + 3(3x) + 3(3)
= 9x² + 9x + 9x + 9
= 9x² + 18x + 9

3xy^z: exponent is not a nonnegative int.
r-2s: it is not a product
(ab)^1/2: exponent is not a nonnegative int.
Answer:
b = 16.5
Step-by-step explanation:
Given
=
( cross- multiply )
9b = 148.5 ( divide both sides by 9 )
b = 16.5
