Answer:
x + 4
Step-by-step explanation:
Noah's age = x
Jacob's age = x – 3
In seven years,
Jacob's age = x – 3 + 7
Jacob's age = x + 4
Answer:
je ne peux rien faire je suis nullu
<h3>
Option A) </h3>
Assuming that (-2)(-7) and 4 + (-18) are equal.
<u>Using the property [-x × -y = x × y = xy]:</u>
- ⇒ (-2)(-7) = 4 + (-18)
- ⇒ (2)(7) = 4 + (-18)
<u>Using the property [x + (-a) = x - a]:</u>
- ⇒ (2)(7) = 4 + (-18)
- ⇒ (2)(7) = 4 - 18
- ⇒ 14 = -14 (False)
<h3 /><h3>Option B) </h3>
Assuming that (2)(7) and 4 + 18 are equal.
- ⇒ (2)(7) = 4 + 18
- ⇒ 14 = 22 (False)
<h3>Option C) </h3>
Assuming that (–2)(7) and 18 + (–4) are equal.
<u>Using the property [-x × y = -xy]:</u>
- ⇒ (-2)(7) = 18 + (-4)
- ⇒ (-)(2)(7) = 18 + (-4)
- ⇒ -14 = 18 + (-4)
<u>Using the property [x + (-a) = x - a]:</u>
- ⇒ -14 = 18 + (-4)
- ⇒ -14 = 18 - 4
- ⇒ -14 = 14 (False)
<h3>
Option D)</h3>
Assuming that (2)(-7) and 4 - 18 are equal.
<u>Using the property [-x × y = -xy]:</u>
- ⇒ (-)(2)(7) = 4 - 18
- ⇒ -14 = 4 - 18
- ⇒ -14 = -14 (True)
Therefore, Option D is correct.
Answer:
The answer is
<h2>36π cubic inches</h2>
Step-by-step explanation:
Volume of a sphere is given by
<h3>
</h3>
where r is the radius
From the question
r = 3 inches
Substitute the value into the above formula and solve for the volume
That's
<h3>
</h3>
We have the final answer as
<h3>36π cubic inches</h3>
