Answer:
10
Step-by-step explanation:
4-1=3 (length of base)
-1-1=-2 (absolute value of height is 2)
3+2+2+3=10
Let smaller no be x and bigger be y
- x+y=39--(1)
- 3x=y+81
- y=3x-81
- y=3(x-27)--(2)
Put it in eq(1)
- x+3(x-27)=39
- x+3x-81=39
- 4x=81+39
- 4x=120
- x=30
Now
The numbers are 9 and 30
First one 3.5 or in fraction 18/5
Second one 16.25
Answer:
sqrt(41)
Step-by-step explanation:
The new point, A' has coordinates=(-3,2). The distance between them is sqrt((-8+3)^2+(6-2)^2)=sqrt(5^2+4^2)=sqrt(41)
Answer:
The height is 35 inches
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh
We know the area is 245 and the base is 14
245 = 1/2 (14)*h
245 = 7h
Divide each side by 7
245/7 =7h/7
35 =h
The height is 35 inches
