3x + 2(-2x + 3) = 50 |use distributive property
3x - 4x + 6 = 50
-x + 6 = 50 |subtract 6 from both sides
-x = 44 |change signs
x = -44
You can’t evaluate that I’m pretty sure
A=<4.60,7.20>
b=<5.10,2.70>
The scalar product, or the inner product, or the dot-product, is by summing the products of the respective directions,
a.b=4.6*5.1+7.2*2.7
=23.46+19.44
=42.9
Answer:
Yes, the two expressions are equivalent
