A is the answer hdndnbdbfb
AD || BC
<span>• AB = CD </span>
<span>• ∠BAD = ∠CDA (a given condition ∵ ABCD is an isosceles trapezium) </span>
<span>The diagonals AC and BD create two ∆'s: ∆ABD, and ∆ACD </span>
<span>The two ∆'s are congruent (SAS). </span>
<span>(S): AB = CD </span>
<span>(A): ∠BAD = ∠CDA
</span><span>(S): AD = DA (common side) </span>
<span>
The corresponding sides of the two ∆'s, BD and AC, are also congruent. </span>
<span>(the two diagonals of the trapezium/trapezoid)
</span>
Add the all numbers Im not sure that's the answer
The domain- Is the function provides an "output" or value for each member of the domain
Range- The difference between the lowest and highest values.
Answer:
x ≥ 1/2
x ≤ -3
Step-by-step explanation:
2x² + 5x - 3 ≥ 0
Factor left side.
(2x - 1)(x + 3) ≥ 0
Set factors in an inequality to 0.
2x - 1 ≥ 0
2x ≥ 1
x ≥ 1/2
You multiply both sides by 2x - 1, so the sign switches.
x + 3 ≤ 0
x ≤ -3
