Answer: A rectangle has <u>2 pairs of opposite sides parallel</u>, and four right angles. It is<u> also a parallelogram</u>, since it has two pairs of parallel sides. A rhombus is <u>defined as a parallelogram </u>with four equal sides, which also has <u>2 pairs of opposite parallel sides.</u>
Step-by-step explanation:
Solve the inequality for x:
5x - 3 ≤ 7x +7
Subtract 7x from each side:
-2x -3 ≤ 7
Add 3 to each side:
-2x ≤ 10
Divide both sides by -2, also when dividing both sides of an inequality you flip the direction of the inequality sign:
x ≥ -5
The dot will be on -5, because the inequality includes equal to, the dot is solid and is greater than, the arrow will point to the right.
The correct answer is D.
This is an equilateral triangle of height a√3/2 where a is the side length. So the area is ½a.a√3/2=a²√3/4.
So a²=25 and a=5cm. Therefore the perimeter is 3a=15cm.
