Answer:
x² + 6
Step-by-step explanation:
Given
(4x² - 6x + 8) - (3x² - 6x + 2) ← distribute by - 1
= 4x² - 6x + 8 - 3x² + 6x - 2 ← collect like terms
= x² + 6
Answer:
x = 11.85
Step-by-step explanation:
x^2+(x-4)^2=202
x^2+(x-4)(x-4)=202
x^2 + x^2 - 4x - 4x + 16 = 202
2x^2 - 8x + 16 = 202
2x^2 - 8x - 186 = 0
Apply the quadratic equation and you'll get x as:
x=11.85 or x=-7.85
x cannot be negative
therefore x = 11.85
The expression s = 5b represents the Sandra rode her bike and the distance Sandra rode, equals 17 miles.
<h3>What is distance?</h3>
Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
We have:
Sandra rode her bike 5 times as many miles as Barbara. If b, the distance Barbara rode, equals 3.4 miles.
b = 3.4 miles
Let's suppose the s is the distance Sandra rode then,
s = 5b
The above expression represents the Sandra rode her bike.
Plug b = 3.4 miles
s = 5(3.4) = 17 miles
Thus, the expression s = 5b represents the Sandra rode her bike and the distance Sandra rode, equals 17 miles.

Very simple. You just use the vectors as normal numbers, and multiply the coordinates with 2 and 4 like this:
2*u = 2* (2,4) = (4,8)
4*w = 4* (-1,3) = (-4,12)
(4,8) - (-4,12) = (8,-4)
So the vector has the coordinates (8,-4)
