Answer:
<h2>
3x = 18</h2>
Step-by-step explanation:
Use the Pythagorean Theorem here:
30² = (3x)² + (4x)², or:
30² = 9x² + 16x² = 25x²
Taking the square root of both sides, we get √(30)² = √(25x²), or:
30 = ± 5x
Neglect -5x, since we are measuring distances, and distances are positive.
Then 5x = 30, and so x = 6
Thus, 3x = 3(6) = 18
Answer:
30
Step-by-step explanation:
Follow the correct order of operations.
There are only multiplications and divisions, so do them in the order they appear from left to right.
625 ÷ 62.5 × 30 ÷ 10 =
= 10 × 30 ÷ 10
= 300 ÷ 10
= 30

Answer:
DC = 21 ; BC = 26
Step-by-step explanation:
The perimeter of a rectangle is given by :
P = 2(length + width)
2x + 3
3x - 1
Perimeter, P = 94
Hence,
94 = 2(2x +3 + (3x - 1))
94 = 2(2x + 3 + 3x - 1)
94 = 2(5x + 2)
94 = 10x + 4
94 - 4 = 10x
90 = 10x
x = 90 /10
x = 9
DC = 2x + 3 = 2(9) + 3 = 18 + 3 = 21
BC = 3x - 1 = 3(9) - 1 = 27 - 1 = 26
