The correct answer is 60cm^2 because the area of a triangle is half base*height -> 30/2*40
If 380 would be 100%
Then use rule of 3
380 ______ 100%
440 ______ y
380y = 440×100%
380y = 440 × 1
Dividing both the sides by 380
y = 440/380
y = 1,158
Let's multiplity "y" by 100
y = 115,8%
As we did have 100% initially
Then the increase will be
The increase = 115,8% -100%
= 15,8%
This would your answer

Answer:
x=1,2
Step-by-step explanation:
x^2-3x+2=0
(x-1)(x-2)
x-1=0
x-2=0
x=1,2
Answer:
(3,2)
Step-by-step explanation:
Since both equations are equal to each others.
2x-4=-2x+8
2x+2x=8+4
4x=12
x=3
Substitute x = 3 in any given equations but I will substitute in the first equation.
y = 2(3)-4
y = 6-4
y = 2
