Quadratic formula using roots to solve for x gives you two values of x
Answer:
w = ( x - 10)
Step-by-step explanation:
area of the garden = x² - 25x + 150.
factorise the expression to find the x values.
x² - 25x + 150 = (x - 15)( x - 10) -15-10 = -25
-15*-10= 150
as the garden is rectangle, it's area will be = lw.
a = l × w
a = (x - 15)( x - 10)
one among them is the width, the other the length. if the length is (x - 15), then reasonably the width will be (x - 10).
hope this helps you, au revoir!
Answer: y=-2/5x+2
Solving Steps:
2x+5y=10 - Move the variable to the right
5y=10-2x - Divide both sides by five
y=2-2/5x - Reorder the terms
y=-2/5x+2
Answer:
20
Step-by-step explanation:
that's wat I got on my test so
Answer : 2x² - 7x - 30
Step-by-step explanation: Multiply the brackets out (first x * 2x then x * 5) (second -6 * 2x then -6 * 5) which will give you 2x² + 5x - 12x - 30. Take away 12 from 5 which gave you the negative 7.
