Answer:
a <em>kite</em> or a <em>square</em>
Step-by-step explanation:
The fact that the diagonals are congruent is irrelevant, unless you also know something about where they cross each other.
A <em>kite</em> has perpendicular diagonals. If they happen to bisect each other, then the result is a <em>rhombus</em>. If the diagonals are congruent, then that rhombus is a <em>square</em>.
<em>Other ways to get there</em>
A pair of congruent diagonals that cross each other symmetrically will define a trapezoid. If they also bisect each other, the result is a rectangle. If the diagonals of that rectangle are perpendicular, then it is a <em>square</em>.
Well to eliminate x you will need to make the positive value of x in one equal the negative value in the other.
hence you can either multiply A by 5/2 or B by 2/5 which brings you to either 2 or 3, but as x is negative in B already, you add. resulting in the answer being the 3rd one down (i think)
Answer:
C or h - 2
Step-by-step explanation:
f(a + h) = a + h - 1
f(a) = a - 1
a + h - 1 - a - 1 = h - 2
