Answer:
39 feet
Step-by-step explanation:
From the question;
let length of ladder =x feet
height of ladder will be=x-3 feet
ground distance of ladder bottom to building=15 feet
Applying Pythagorean relation
a²+b²=c²
where a=15 feet b=x-3 feet and c=x feet thus
x²-15²=(x-3)²
x²-225=x²-6x+9
collect like term
x²-x²-225-9=-6x
-234= -6x
x= 39 feet length of ladder
distance from ground to top of ladder= 39-3=36 feet
Answer:

(1/2x5x6)x2+(11x5)x2=140
140 square centimeters
To find the unit rate, we need to set the number of days to 1. Therefore, we will divide by 7. We also have to divide 42 by 7 to make sure the equation stays proportional. Using this knowledge, we can see that if the corn grew 42 inches in 7 days, it grows 6 inches per day.
