Answer:
58 in
Step-by-step explanation:
The fact that the rectangles are congruent means both have a length of 18 in and a width of 11 in. The perimeter is ...
P = 2(L +W)
P = 2(18 in + 11 in) = 2(29 in)
P = 58 in
The perimeter of KHGJ is 58 inches.
Answer:
Step-by-step explanation:
Step 1: Flip the equation.
Step 2: Subtract D from both sides.
Step 3: Divide both sides by Dr.
Answer:
The answer is B.
Step-by-step explanation:
3< x _<5
When working with very large or very small numbers, scientists, mathematicians, and engineers use scientific notation to express these quantities. Scientific notation is a mathematical abbreviation, based on the idea that it is easier to read an exponent than to count many zeros in a number. Very large or very small numbers need less space when written in scientific notation because the position values are expressed as powers of 10. Calculations with long numbers are easier to do when using scientific notation
The given statement is "nine times five less than twice x".
So, twice of x can be written as 2x and nine times five is 9*5.
Now 9*5 less 2x means we need to take out 9*5 from 2x.
Hence, this statement will be converted into an algebraic expression as follows:
2x-9*5
