If f(x) = 4x + 10, which expression represents f(x2 + 2)?

1 answer:

8 0

In order to determine the answer to this item, we just have to substitute x² + 2 to all x's of the first function. That is,
f(x) = 4x + 10
will become,
f(x²+2) = 4(x²+2) + 10
Simplifying will give us an answer of,
f(x²+2) = 4x²+18

Which of the objects shown above are pyramids?

PolarNik [594]

<h3>Answer: A and B (first answer choice)</h3>

Explanation:

Both figures shown in A and B are triangular pyramids. The base is a triangle, and the lateral sides are also triangles. Another example would be rectangular pyramids where the base is a rectangle, and the lateral sides are triangles.

Choice C is ruled out because cones aren't considered pyramids.

Choice D is a combination of a rectangular prism, and a rectangular pyramid stacked on top, so it's not purely a pyramid only. We can rule out choice D.

The length of the side sqaure A is 50% OF THE LENGTH OF THE SIDE SQUARE b

UNO [17]

Let's say the side length of square A is x, which means the side length of square B is 2x.

Then, the area of square A can be written as , and the area of square B can be written as .

There's no diagram here with shaded region, so I'll just find the area of square A as a percentage of the area of square B:

= 1/4 = 25%

So, the answer is 25% (note this is the answer to the question: "express the area of square A as a percentage of the area of square B; there is no diagram showing me where the shaded area is, so I cannot answer the original question
