Answer:
f(x) = x² + 2x + 1
Step-by-step explanation:
you know how to multiply 2 expressions ?
let's say in general we have
(a + b)(c + d)
you take one part of one expression and multiply it with all parts of the other expression, then you take the second part of the first expression and multiply it with all parts of the other expression, then a potential third part, then a fourth part and so on, and you add all these things together (well, depending on the actual signs, of course).
so, we get for this simple generic example
a×c + b×c + a×d + b×d
now we use that understanding for our question here.
(x+1)(x+1) = x×x + 1×x + x×1 + 1×1 = x² + x + x + 1 = x² + 2x + 1
Answer: 2a*4*4*4*4= x (Vote me brainliest please)
Step-by-step explanation: Exponents are simply telling you to multiply the base number or expression by that many times.
Answer: The product of (-4)(-8) is 32. Multiply two negatives makes it positive. So just think of it as 4 times 8. Which is 32.
Answer:
12 cm
Step-by-step explanation:
The question is not complete Let us assume the base has a length of 15 cm and width of 10 cm.
A pyramid with a rectangular base is a rectangular pyramid. Its base is rectangular and on each side of the base, it has a triangular face known as lateral face.
The volume of a rectangular pyramid is one third of the product of the length of the base, breadth of the base and height of the pyramid given by:
Volume = (length × breadth × height) / 3
Let us assume the base has a length of 15 cm and width of 10 cm.
Given that the volume = 600 cm³.
Volume = (length × breadth × height) / 3
600 = (15 × 10 × height)/3
1800 = 150 × height
height = 1800 / 150
height = 12 cm
