70+68= 138
138 is the answer because by the triangle sum theorem says all the inside angles of a triangle equal 180 degrees and a straight line is 180 degrees so to find x you just must add up the other two sides of the triangle

Kevin decides to build a square for his play park. If the area of the room is 4x^2 + 28x + 49 square feet, what is the length of

leva [86]

We have to factor becasue
area=legnth times width
area=4x^2+28x+49
area=(2x+7)(2x+7)
area=(2x+7)^2
legnth =width

we arent' given area so we can't solve
but, , since it is a squaer room, legnth=width so √area=legnth=width

Answer:

I'm not SUPER sure but, it only can exist where there is a region in a planetary system where liquid water might exist on the surface of a planet. That puts it in the "habitable zone" which is where it can exist.

What is the next fraction in this sequence? Simplify your answer. 3/4, 1/4, 1/12, 1/36

antiseptic1488 [7]

Hey their,

3/4
1/4
1/12
1/36
0/60

The pattern is -1/x every 2 +x/8

How i got this was 36/12=3
3*12=36
so 60-36=24
24x3/2+24=60
then 60/5=12

Hopethis helped

Answer:

$f(x)=\left \{\begin{array}{rl}26^{\frac{k}{2}}&\text{for k even}\\26^{\frac{k+1}{2}}&\text{for k odd}\end{array}\right.$

Step-by-step explanation:

Half the length of the palindrome can be any possible sequence of the 26 available letters. The other half is constrained to be the reverse of the same sequence. For odd length sequences, the middle letter can be any of the 26.

So, for k even, the number of palindromes is 26^(k/2). For k odd, the number is 26·26^((k-1)/2) = 26^)((k+1)/2).

Please help. I'm stuck.

The root $\sqrt{10}$ can be converted into the power $10^{ \frac{1}{2} }$ . Therefore we can rewrite the problem as $(10^{ \frac{1}{2} } )^ {\frac{3}{4} x}$ and then follow the exponent rules about a power to a power, multiplying 1/2 and 3/4 together.

Thus the problem becomes $10^{\frac{3}{8}x}$ , which then can be turned into $\sqrt[8]{10} ^{3x}$ , making the last option our answer.
