<span><u><em>The correct answers are:</em></u>
A, B and C.
<u><em>Explanation</em></u><span><u><em>: </em></u>
<u>A parallelogram</u> is a quadrilateral with both pairs of opposite sides parallel.
<u>A rectangle</u> is a parallelogram with all right angles, so yes, every rectangle is a parallelogram.
<u>A square</u> is a parallelogram with all right angles and all congruent sides; since it is a parallelogram with all right angles, every square is a rectangle.
<u>A rhombus</u> is a parallelogram with all congruent sides.
Since a square is a parallelogram with all congruent sides, then every square is a rhombus.
<u>A </u><u>trapezoid</u> is a quadrilateral with one pair of parallel sides. Since a rhombus is a parallelogram, with 2 pairs of parallel sides, rhombus are not trapezoids.</span></span>
Answer:
Yes
Step-by-step explanation:
If the largest number squared is equal to the sum of the squares of the other 2 numbers, then Pythagorean triple
largest number = 7.5 and 7.5² = 56.25
2.1² + 7.2² = 4.41 + 51.84 = 56.26
Thus 2.1, 7.2 and 7.5 create a Pythagorean triple
B was the answer when I graphed using Desmos
Answer:
x=7
Step-by-step explanation:
6 - 6x = 5x – 9x - 8
Combine like terms
6-6x = -4x-8
Add 6x to each side
6-6x+6x =-4x-8+6x
6 = 2x-8
Add 8 to each side
6+8 = 2x-8+8
14 = 2x
Divide each side by 2
14/2 =2x/2
7 =x
