Answer:
She should have multiplied one half (4)(3.5) by 5 squared.
Step-by-step explanation:
We are given that
Base of triangle=b=4 cm
Height of triangle=h=3.5 cm
Area of triangle=
After enlarged
Scale factor=5
New base of enlarged triangle=b'=4(5) cm
Height of enlarged triangle=h'=3.5(5) cm
Area of enlarged triangle=

She should have multiplied one half (4)(3.5) by 5 squared.
The ratio would be 4:6 because there are 6 number in total and 4 of them are odd numbers.
It is 20.000 plus 2.000 plus 50 plus 6
|x - 2x/5| <= 10
|5x - 2x| <= 50
3x <= 50
x <= 50/3
-|5x - 2x| <= 50
-3x <= 50
x >= - 50/3
answer
-50/3 <= x <= 50/3
