Answer:
Step-by-step explanation:
The distributive says that:
To find the product of :
then;
Using distributive property we have;
Combine like terms;
Therefore, the product of is,
The product of (2x - 1)(x + 4) is .
Here, we have,
To find the product (2x - 1)(x + 4), we need to use the distributive property to multiply each term in the first expression (2x - 1) by each term in the second expression (x + 4).
Using the FOIL method (First, Outer, Inner, Last), we multiply the corresponding terms:
(First terms)
(2x) * (4) = 8x (Outer terms)
(-1) * (x) = -x (Inner terms)
(-1) * (4) = -4 (Last terms)
Now, we combine the products:
Simplifying further:
So, the product of (2x - 1)(x + 4) is .

a.) Accurately sketch the plane on the set of axes, showing all your calculations below.
b.) The three planes of the axes and the plane you have sketched create a triangular pyramid. Find the volume of this pyramid, showing the formula you are using and all
calculations below.
My Answer:
a. I started off by finding my x-intercept. To find my x-intercept I substituted y and z with 0. So: x + 3(0) + 2(0) = 6. After multiplying and adding, I end up with x = 6. So my x-intercept is (6, 0, 0,). T find my y-intercept I substituted x and z with 0. So: 0 + 3y + 2(0) = 6. After multiplying and adding, we come up with 3y = 6. Now we divide each side by 3 to get y = 2. So my y-intercept is (0, 2, 0). To find my z-intercept, I substituted x and y with 0. So, 0 + 3(0) + 2z = 6. After multiplying and adding, I get 2z = 6. Now I divide each side by 2 to get z = 3. So my z-intercpet is (0, 0, 3). After I plotted the points and connected them, they formed a triangular pyramid.
So thats how much i got. I cant seem to figure out how to get the volume. please help.
Answer:
Volume of the pyramid = 6 cubic units
Step-by-step explanation:
The volume of a triangular pyramid is: V = (1/3)*A*H
where A is the area of the triangle base, and H is the height of the pyramid.
Taking the triangle formed in the x-y plane as the base, its area is computed as follows:
A = (1/2)*6*2 = 6 square units
where 6 and 2 are the measure of the two perpendicular sides of the triangle. This is taken from the x-intercept point (6, 0, 0) and y-intercept point (0, 2, 0).
The height of the pyramid is then the measure of the z-intercept point (0, 0, 3), that is, 3. Replacing in volume formula:
V = (1/3)*A*H
V = (1/3)*6*3
V = 6 cubic units
Thank you!!
Answer: The maximum number of people they could have at the party is 18.
Step-by-step explanation:
$250 - $75 = $175
$175 - $47 = $128
$128 / $7 = 18.28
Hope this helps:)
