Answer:
Step-by-step explanation:
m= y2-y1/x2-x1
m= 3-(-2)/ 3-0
m=5/3
y=mx+b
3= 5/3(3)+b
3= 5+b
-5 -5
-2=b
Answer:
11r + 10s
Step-by-step explanation:
-20+14m=10m+16
-10m. -10m
-20+4m=16
+20. +20
4m=36
/4. /4
m=9
Length of the rectangle is 40 meters.
Step-by-step explanation:
- Step 1: Ratio of width:length = 4:5, so let width be 4x and length be 5x. Find the length if area = 2000 sq. m
Area of the rectangle = length × width
2000 = 5x × 4x
2000 = 20x²
⇒ x² = 2000/20 = 100
∴ x = 10
4x = 40 m
Answer:
116 centimeter squared
Step-by-step explanation:
La²+8La+16 = La²+70
Step-by-step explanation:
8La+16 = 70
8La=70-16
La=54/8
La= 6.75
Area b = (6.75+4)*(6.75+4)
Area b = 10.75*10.75
Area b =115.563
