Answer:
rectangle, square
Step-by-step explanation:
A rectangle always has 4 congruent angles. A square is a rectangle, so a square always has 4 congruent angles.
A parallelogram and a rhombus may or may not have 4 congruent angles.
Answer: rectangle, square
Answer: 1: 45
Hope this helps!
B) Is correct and
as-well is A.
B had no repeated values and A has none as-well.
And for A the curve increases without a repeated value (as drawn in the picture)
For D 2 was repeated.
and for C, 3 was repeated.
Answer:
D- F(x) > 0 over the intervals ( –2.5, –0.75) and (0.75, ∞).
Answer:
BC = 23
Step-by-step explanation:
Since ∠ A = ∠ C then the triangle is isosceles with AB = BC, that is
3x + 14 = x + 20 ( subtract x from both sides )
2x + 14 = 20 ( subtract 14 from both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Thus
BC = 3x + 14 = 3(3) + 14 = 9 + 14 = 23
