Formula for this case is
(a+b)∧3=a∧3+3a∧2b+3ab∧2+b∧3
(2x+5)∧3=(2x)∧3+3*(2x)∧2*5+3*2x*5∧2+5∧3=8 x∧3+3*4x∧2*5+3*2x*25+125=
=8x∧3+60x∧2+150x+125
Good luck!!!
Answer:
1
Step-by-step explanation:
how long is |MN| when you measure it and do you know anything about the length of |NO| and |OP|?
assuming |MN|= 7.7 ; |NO|= 4.7 ; |MO|= 5.5:
o²= m²+n²
= 4.7²+5.5²
=52.34
o=V52.34
≈7.23
0.75^2 = 0.5625.....sq rt 0.5625 = 0.75
<h2>
Hello!</h2>
The answer is: Angle B is 30°
<h2>
Why?</h2>
Since we know that both sides, a and b are equal to 2, and angle A is equal to 30°, we can conclude that angle B is also equal to 30°. Also, we can know that the other angle (C) will be equal to 120° since the sum of all the angles in a triangle will be always equal to 180°.
Have a nice day!
