Answer:
1. A. contain a right angle
1. B. opposite sides are parallel
2. (c) 2 pairs of parallel sides
3. (b) 2 sides of equal length
Step-by-step explanation:
Here you are asked to find patterns and to make use of the definitions of different geometric figures.
<h3>1.</h3>
The figures in Circle A do not all have the same number of sides, or sides of the same length. However, they do all have at least one right angle.
The figures in Circle B are rectangles and parallelograms. The attributes listed in question 2 can be used here. They all have two pairs of parallel sides.
<h3>2.</h3>
As we observed in question 1, rectangles and parallelograms share the feature of 2 pairs of parallel sides.
A kite may have 2 pairs of equal-length sides. While a square and a rhombus have 4 sides of equal length, that description is not true of rectangles and parallelograms in general.
Angles in a rectangle are all 90°, while those in a parallelogram may not be. The offered descriptions of angles do not apply to apply to both shapes.
<h3>3.</h3>
An isosceles triangle has two sides equal length and two equal angles. An equilateral triangle is a special case of an isosceles triangle in which all three sides are equal, as are all three angles. The description that applies to both kinds of triangles is 2 sides of equal length.

4.063 x 10 to the fourth power
X+3x=36 reduces to 4x=36, so when you divide both sides by 4, x=9
Answer: 1/25
Step-by-step explanation:
Number of balls = 10
Number of purple balls = 2
Since it's probability with replacement,
Probability of picking a purple ball the first time = 2/10 = 1/5
Probability of picking a purple ball the second time = 2/10 = 1/5
Therefore, the probability of picking a purple ball both times will be:
= 1/5 × 1/5
= 1/25
