You can get this answer by setting the legs equal to x and x+4 and the hypotenuse as 2x-4. Then use the Pythagorean Theorem and the quadratic equation to solve.
The time it took to mow all the lawns including the break he took was 1 3/4+1 1/5+1 1/5+3/4=
2 1/2+2 2/5= 4 9/10 which is 4 hours and 54 minutes and if he got done at 4:15pm then he started 4 hours and 54 minutes before at
C. 11:21 A.M.
Answer:
10 feet
Step-by-step explanation:
base= x feet
height=(6+x) feet
area= (6+x)x=160
=6x+x²=160 ==> x²+6x-160=0
factories the eqn obtained....
(x-10)(x+16)=0
x= 10 or -16
since length cannot be negative, x=10
since the base = x feet
base=10 feet
