Answer:
Step-by-step explanation:
<u>B is the midpoint of AC. It means:</u>
<u>And we have a common side BD:</u>
a) As per above we only have two sides congruent and this information is not sufficient to state the triangles ABD and CBD are congruent.
b) <u>In addition to the two sides we also have:</u>
With this additional information we have three sides congruent, so the triangles are congruent by SSS postulate.

Answer:
3(7 + 4)2 − 24 ÷ 6 = 62
Step-by-step explanation:
3(7 + 4)2 − 24 ÷ 6 is the given expression.
Now, by the rule of BODMAS, where B = Bracket, O= of, D = divide,
M = multiplication, A = addition and S = subtraction
we try and solve the following expression in the same order.
Solving the bracket first, we get
3<u>(7 + 4)</u>2 − 24 ÷ 6 = 3(<u>11</u>)2 − 24 ÷ 6 =<u> 66</u> − 24 ÷ 6
Next, we solve divide,
66 − <u>24 ÷ 6</u> = 66 - <u>4</u>
Next, solving the subtraction, 66 - 4 = 62
Hence, 3(7 + 4)2 − 24 ÷ 6 = 62
