Answer:
(x+1)(x-5)
Step-by-step explanation:
(x+a)(x+b)=x²-4x-5
then a+b=-4 and a*b=-5
so a=-1 and b=5
Answer:
He paid $ 531.8 for it
Step-by-step explanation:
Given that Joshua sold his bike for $585
Since he sold it for 10% less than he paid for it, let the amount he paid for it be x.
Then
x= $585 -(10 % of x)
=$585 - (0.1 x)
<u>Add 0.1x to both sides</u>
(1+0.1)x=585
1.1x=585
<u>Divide both sides by 1.1</u>
x=585/1.1
=531.8

Slope = 5
y = mx + b
2 =5(4) + b
b = 2 - 20
b = -18
<span>point-slope equation
y - 2 = 5(x -4)
</span><span>slope-intercept equation
y = 5x - 18
standard form
5x - y = 18</span>
Answer:
x^2 + (y-10)^2 = 64 I think
Answer:
14
Step-by-step explanation:
First, we have to get the breadth value.
By the pythagoras theoreom,
Diagonal²=length² + breadth²
breadth = √( Diagonal²- length²)
breadth = √( 5² - 4²)
breadth = √9
breadth= 3
Perimeter of a rectangle = 2x ( length + breadth)
= 2 x ( 4 + 3)
= 2 x 7
= 14
