Step-by-step explanation:
(3x-14)+9x=90, thus,
((3x-14)+9x)+90=180
90+90=180

Answer:
The correct option is e) 27.
Step-by-step explanation:
Consider the provided information.
We need to find how many palindromes are possible If 5-digit palindromes are formed using one or more of the digits 1, 2, and 3,
The number should be in the form of XYZYX
Now for the first digit we have 3 choices, for second digit we also have 3 choices, for third digit we also have 3 choices but for fourth and fifth digit we have only one choice.
Therefore the number of possible palindromes are:
3 × 3 × 3 × 1 × 1 = 27
Hence, the correct option is e) 27.

Answer:
5.946 cm
Step-by-step explanation:
Using the Pythagorean Theorem, we know that in a right angle triangle to find the longest side we must use the equation a^2 = b^2 + c^2
A is the longest side while b and c are the other two sides
To find one side we must use
b^2 = a^2 - c^2
a squared = 6.9 squared - 3.5 squared
a^2 = 35.36
square root 35.36 to get a
a = 5.946427499
a (3 d.p.) = 5.946
