Answer:
You should provided some numbers to go off
Step-by-step explanation:
so I couldn't really give you a straight up answer
He has eaten 7/21 already. if he eats 9/21 from the 14/21 left, he will have 5/21 left. the answer is d
Distribute then multiply 6x to all the terms inside parenthesis remember order of operations starting from left to right when solving expressions so the when you distribute
is 30x3-6x2 the 3 and 2 after x represent x cubed and squared
Answer: area
Step-by-step explanation:
Area is solved with L * W
Volume is solved with L * W * H
Using these formulas we can see that area uses 2-dimensions, the length and the width, while volume uses 3.
Answer:
there are two complex roots
Step-by-step explanation:
Recall that for a quadratic equation
y = ax² + bx + c
the solution given by the quadratic formula is
x = ( -b ± √discriminant) / 2a
if the discriminant is negative, the radical term will become √ (negative number), which we know gives complex solutions. Hence we can eliminate real roots as possible answers.
Also notice that the "±" sign in the quadratic formula means that you will get 2 possible solutions:
x = ( -b + √discriminant) / 2a
or
x = ( -b - √discriminant) / 2a
Hence we know we will get 2 solutions.
Combining our findings, we can conclude that if the discriminant is negative, we will get 2 complex roots.
