circular cardboard with an area between 154 in² and 616 in²
Radius is between 7 inches and 14 inches. ⇒ A) 7 < r < 14
√18 + √2 = √9 *2 + √2 = 3√2 + √2 = (3+1) √2 = 4√2
D) It is irrational and equal to 4 multiplied by the square root of 2.
Answer:
Step-by-step explanation:
So put the 0-3 to the y2, 3-6 to the y4 and 6-9 to the y2
Answer: Therefore it must be the first one, 40
Step-by-step explanation: Vertical angles are always congruent, which means that they are equal. x = 40
C because the x-axis and the y-axis are switched, basically.
Answer:
PR = 20
Step-by-step explanation:
The perimeter is the sum of the 3 sides, thus
4z + z + 3 + 3z + 2 = 45 ← simplify left side
8z + 5 = 45 ( subtract 5 from both sides )
8z = 40 ( divide both sides by 8 )
z = 5
PR = 4z = 4 × 5 = 20
