<span>To find the area of a triangle, multiply the base by the height, and then divide by 2.
Base=10 cm
Height= 12 cm
10*12=120
120/2=60
60 square meters.

Answer:
As i multiplied i got the answer like this
18x^3+6x^2+14x-72
Answer:
Step-by-step explanation:
18*18 = 324
So 18 is the closest integer to 
The numbers are "x" and "y", therefore, we suggest this system of equations:
x-y=14
xy=1800
We can solve by substitution method.
x=14+y
(14+y)y=1800
14y+y²=1800
y²+14y-1800=0
Now, we solve this square equation:
y=[-14⁺₋√(196+7200)] / 2=(-14⁺₋86)/2
We have two solutions:
y₁=(-14-86)/2=-50 ⇒x=14+y=14-50=-36
y₂=(-14+86)/2=36 ⇒x=14+y=14+36=50
Answer: we have two solutions:
Solution1: The first number is -36 and the other number is -50
Soltuion2: The first number is 50 and the other number is 36
