Answer:
didn't give clear instructions on what to do. I just assumed you add them. answer is down below. :)
Step-by-step explanation:
if ur supposed to add them then
1. 1/8 + 8/8 + 3/8 = 12/8 = 1 1/2
2. 1/4 + 2/4 + 1/4 = 4/4 = 1
3. 1/8 + 8/8 + 4/8 = 1 5/8
4. 1/4 + 1/4 + 2/4 = 4/4 = 1
5. 1/4 + 1/4 + 1/4 + 1/4 = 1
The graph is at a slope:1 with a y-intercept:-4
Answer:
Step-by-step explanation:
hello :
let :
y : the length , x : the width , A : the area, x and y positifs numbers (y>x)
you have the system : xy=180....(*)
y=x+8...(**)
put the value for y by (**) in to(*) : (x+8)x=180
x²+8x-180 =0......a=1 b=8 c = -180
∆ = b²- 4ac
∆ = 8²- 4(1)(-180)=384=28²
X1 = ( -b - √∆)/2a = (-8-28)/2 = -15 refused
X2= ( -b + √∆)/2a = (-8+28)/2 = 10
x=10 but : y=x+8
y = 10+8 =18
The length of the rectangle is...18...cm.
The width of the rectangle is...10...cm.
