First off, remember PEMDAS. Then replace the variables with the values.
3(2x3)^2
First distribute the exponent to the value on the inside.
3(4x9)
Then multiply the 4 and 9.
3(36)
After that just distribute the 3.
3x36 = 108.
X^2 -(y^2-x-1). >>simplify
=x^2+ (-4)(y^2)+(-4)(-x)+(-4)(-1). >>>> distribute
= x^2 -4y^2 + 4x +4 >>>>answer
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Sarah, Jose and you live in the same street:
Distance between you and Jose = 5 blocks
Distance between Jose and Sarah = 2 blocks
Distance (b) between you and Sarah:
Since it isn't stated whether Sarah lives closer to you than Jose or vice versa ;
Then;
Distance b between you and Sarah will be :
(Distance between you and Jose ± distance between Jose and Sarah)
b = (5 ± 2)
b = (5 + 2) or (5 - 2)
b = 7 blocks or 3 blocks
