Answer:
A non-square rhombus is not a rectangle.
Step-by-step explanation:
A parallelogram is a quadrilateral (four-sided figure) that has two pairs of parallel sides.
A rectangle is a parallelogram with four right angles.
If a parallelogram does not have four right angles, then it is not a rectangle. However it is still a parallelogram, as it has two pairs of parallel sides.
Answer:
x=7
Step-by-step explanation:
HI + IJ = HJ
3x-5 + x-1 = 7x-27
Combine like terms
4x-6 = 7x-27
Subtract 4x from each side
4x-6 -4x= 7x-27-4x
-6 = 3x-27
Add 27 to each side
-6+27 = 3x-27+27
21 = 3x
Divide by 3
21/3 = 3x/3
7 =x
Answer:
23:119
Step-by-step explanation:
all pens:
77 blue + 23 red + 15 pink + 4 purple
77 + 23 + 15 + 4 = 119
119 total pens
23 red / 119 total
23/119
23 is prime, so this cannot be simplified further
the ratio of red : total pens is 23:119
