Answer:
B
Step-by-step explanation:
Equilateral because the sides are equal
Answer:
D) -30x^2 -64x -18
Step-by-step explanation:
Given:
f(x) = 6x +2 and g(x) = -5x - 9
f(x).g(x) = (6x + 2) (-5x - 9)
Use distributive property
= 6x(-5x -9) + 2(-5x - 9)
= -30x^2 - 54x - 10x -18
= -30x^2 -64x - 18
Answer: d) -30x^2 -64x -18
Thank you.
If you wrote the expression correctly, then
Is a polynomial, and thus defined everywhere: its domain is the set of all real numbers.
If, by chance, you meant
Then we must exclude the point x=4 from the domain, since that value would cause the denominator to vanish. So, the domain would be the set of real numbers, minus the number 4.
This is. lol, just messing w/ ya. Mine would probably be any math problem>:[
Which set of side lengths, in inches, will form a triangle? a 3.5, 7.2, and 3.0 b 10.0, 4.6, and 5.3 c 5.5, 4,9, and 10.5 d 3.2,

Answer:
The correct answer is D
Step-by-step explanation:
To form a triangle, the sum of ANY two sides of the triangle must be greater than the length of the third side.
Looking at the first: 3.5+3.0 = 6.5 < 7.2, therefore it can't form a triangle since the sum of a pair of sides is less than the third side.
Looking at the second: 4.6 + 5.3 = 9.9 < 10.0, it's the same as the first.
Looking at the third: 5.5 + 4.9 = 10.4 < 10.5, it's the same as the first and second.
Looking at the last: 3.2 + 5.9 = 9.1 > 4.5, 3.2 + 4
5 = 7.7 > 5.9 and 5.9 + 4.5 = 10.4 > 3.2. Obviously, this fulfils the condition of a triangle. Any two sides is greater than the third, therefore the correct answer is D.
