Answer:
75 feet
Step-by-step explanation:
the shadow to the object would be a 4:5 ratio
since the shadow of the flagpole is 60 ft,
4x=60 so x would =15
then you multiply 15 by 5 and end up with 75
4x + 28
Distribute the four to both numbers to and add the x to the four for 4x 4 x 7= 28 so
4x + 28
Answer:
Step-by-step explanation:
x^2+20=2x move 2x to the left
x^2-2x+20=0
Quadratic formula =
x=1± i√19
16+16+16+9+9=32+16+9+9=48+9+9=57+9=66
The answer is 66
