Answer:
16 ft³
Step-by-step explanation:
4ft x 2ft x 2ft = 4ft x 4ft = 16 ft³
Answer:
<A = <B
=> 8x - 8 = 5x + 25
<=> 3x = 33
<=> x = 11
with x = 11 => mB = 5.11 + 25 = 55 + 25 = 80⁰
Answer:
x=6
Step-by-step explanation:
I would look at this triangle and notice that x can be solved by setting up a ratio.
I generally put the short side of the triangle on the top and the long side on the bottom
4/x = x/9
You then cross multiply to get 36=x^2, or +-6=x
A length of a triangle cannot be negative, so we are left with the answer x=6
Answer:
255
Step-by-step explanation:
The recursive formula is used to find the terms one-by-one, unless you convert it to an explicit formula.
first term (given): 3
2nd term = 4·3 +3 = 15
3rd term = 4·15 +3 = 63
4th term = 4·63 +3 = 255
_____
Looking at the sequence of terms, we see that an explicit formula might be ...
an = 4^n -1
Then the 4th term is
a4 = 4^4 -1 = 256 -1 = 255

<em>Comment on the problem statement</em>
This is NOT an Arithmetic Progression. An arithmetic progression has a <em>common</em> <em>difference</em> between terms. Here, the differences are 12, 48, 192, numbers that are <em>different</em> from one pair of adjacent terms to the next.
You you use the conjugate of sqrt17 - sqrt 2 which is sqrt17 + sqrt2
so the fraction is sqrt17 + sqrt2
------------------
sqrt17 + sqrt2
