r=-\dfrac{7}{2}\div7\\
r=-\dfrac{7}{2}\cdot\dfrac{1}{7}\\
r=-\dfrac{1}{2}$

What is the area of a rectangle that is 11ft by 2ft?

Anastaziya [24]

Answer: 22 ft²

Step-by-step explanation:

To find the area of a rectangle, we multiply the length and width. It doesn't matter which is which as we get the same answer in the end.

Given information:

Length = 11 ft

Width = 2 ft

Area = length x width

Area = 11 ft x 2 ft = 22 ft²

You'll notice the unit is feet squared or ft², because feet x feet gives us feet².

Someone help me with these problems ASAP

Komok [63]

2x^4 + x^3 − 8x^2 − 4x
= x ∙ (2x^3 + x^2 − 8x − 4)
= x ∙ (x^2 ∙ (2x + 1) − 4 ∙ (2x + 1))
= x ∙ (x^2 − 4) ∙ (2x + 1)
= x ∙ (x − 2) ∙ (x + 2) ∙ (2x + 1)

Thus the roots are:
x ∙ (x − 2) ∙ (x + 2) ∙ (2x + 1) = 0
⇒ [x = 0] or [x − 2 = 0] or [x + 2 = 0] or [2x + 1 = 0]
⇒ [x = 0] or [x = 2] or [x = −2] or [x = − 1/2]

Which expression is equivalent to

KonstantinChe [14]

Given the expression:

$\sqrt[4]{ \frac{24x^{6}y}{128x^{4}y^{5}}}$

Simplifying:

$\sqrt[4]{ \frac{3x^{2}}{16y^{4}}}$

Then the answer is:

$\frac{ \sqrt[4]{3x^{2}}}{2y}$

Is 3/8 estimated to be closer to 0 or 1?

kolezko [41]

The cut-off point is 0.5: higher than this would be closer to 1, and lower would be closer to 0

and 3/8 is lower than 0.5: we know this because a bigger number, 4/8 is equal to 0.5

so it's closer to 0!

classify each angle pair using all the names that apply using the diagram on the left , answering 1 2 3 4 and 5 , explain why.(

vredina [299]

Answer:

see the attachment

Step-by-step explanation:

1. Two angles that sum to 90° are complementary, whether they are adjacent or not. Angles LMN and NMP are also adjacent.

2. Vertical angles created by two distinct lines are never adjacent. The sides of the angles are created by the same lines, and the angles share a vertex, but there is no ray that is a side common to both angles.

3. Angle GMK is supplementary to angle JMG.

4. Vertical angles are congruent. See question 2.

5. See question 1.
