PLEASE HELP! Observe the following quadrilaterals. They each have been labeled with a specific name. Determine if the quadrilate
ral was given the correct name and explain your reasoning below each quadrilateral
2 answers:
Rectangle:
If each angles of a quadrilateral is 90 and opposite side are equal then it is a rectangle.
Rhombus:
If in a quadrilateral, opposite angles are equal and all sides are equal, then it is a Rhombus
Answer:
Rectangle:
A rectangle has 4 interior 90° angles and 2 sets of parallel sides (11.2,11.2 and 9.6,9.6) so therefore it was correctly named
Rhombus:
Opposite angles in a rhombus are equal (102° and 102° and 78° and 78°)
and has two pairs of parallel sides; one of these pairs being diagonal lines (13.2,13.2)

Answer:
3(8-4x) < 6(x-5)
24-12x < 6x-30
24+30 < 6x+12x
54 < 18x
54\18 < x
3 < x
It means the ans is option no. b
Answer:
9x + 7
Step-by-step explanation:
Given
6x + 5y + 3x + 7 - 5y ← collect like terms
= (6x + 3x ) + (5y - 5y ) + 7
= 9x + 0 + 7
= 9x + 7
Step-by-step explanation:
x² + 4x - 9
= (x + 2)² - 13
a = 2, b = -13.
