Yeah I ordered something from Chewy and it got delivered by ups
The probability of getting a green marble here is 7/10
Surface area = 2(19 x 15) + 2(15 x 13) + 2(13 x 19)
Surface area = 570 + 390 + 494
Surface area = 1454 cm²

Answer: Surface area = 1454 cm²

The triangle are similar because they satisfy the AAA postulate : Triangle ABC ~ Triangle PQR ( AAA similarity postulate )
<h3>Meaning of congruent triangles</h3>
A triangle can be defined as a plain shape that has three sides and three angles.
Congruent triangles are triangles that satisfy one or more congruence postulates or laws. The triangles could either be similar based on their angles or sides or angles and side being similar.
In conclusion, The triangle are similar because they satisfy the AAA postulate : Triangle ABC ~ Triangle PQR ( AAA similarity postulate )

Answer:
a = √[(c — b)(c + b)]
Step-by-step explanation:
a^2 + b^2 = c^2
We can make "a" the subject by doing the following:
a^2+ b^2 = c^2
Subtract b^2 from both side:
a^2 = c^2 — b^2
Take the square root of both side
a = √(c^2 — b^2)
Since we have difference of two squares, we can simplify further as:
a = √[(c — b)(c + b)]
