Apply pythagorean theorem

L=12ft
B=9ft

Diagonal

√L²+B²
√12²+9²
√144+81
√225
15ft

Again apply

H²=P²+B²
H²=3²+9²
H²=9+81
H²=90
H=√90ft
H=9.5ft

solve this word problem leading to quadratic equation: the area of a rectangle is 60cm². The length is 11cm more than the width.

morpeh [17]

Answer:

Step-by-step explanation:

let : x The length and y the width you have this system :

xy =60....(1)

x = y+10...(2)

put the value for x in (1): (y+10)y =60

the quadratic equation is : y² +10y - 60 = 0

Δ =b² - 4ac a = 1 b= 10 c= - 60

Δ =10² - 4(1)(-60) = 324 =18²

y 1 = (-10-18)/2 negatif...... refused

y 2 = (-10+18)/2 =4

the width is 4

{y=-x+1<br> {y=4x-14<br> please help me <br> my paper is due today

Temka [501]

$- x + 1 = 4x - 14 \\ - x - 4x = - 14 - 1 \\ - 5x = - 15 \\ x = 3$

Substitute x = 3 in any given equations. I will do in y = - x + 1

$y = - x + 1 \\ y = - 3 + 1 \\ y = - 2$

Therefore the answer is (3,-2)
