<span>61/100- 7/25
Multiply until both fractions have the same common denominator
61/100 - 28/100
Subtract the numerators but NOT the denominators

Answer:
50
Step-by-step explanation:
and
can be expressed in complex form, with
= i
=
=
×
= 8i
=
=
×
= 4i
the factors can then be expressed as
(6 + 8i)(3 - 4i) ← expand using FOIL
= 18 - 24i + 24i - 32i² [ i² = (
)² = - 1 ]
= 18 - 24i + 24i + 32 ← collect like terms
= 18 + 32 + 0
= 50
Answer:
Size 9
Step-by-step explanation:
The range is the highest value - the lowest value.
If the range is three, therefore the highest value - lowest value is 3
If 2 people in the family wear size 6, we can count that as 1 value. Since the question says that his shoe size can't be 3, so we let x be the number with the higher value.
x - 6 = 3
x = 9
Therefore Lee's shoe size is 9
X=29/2, 15/2
this is the answer hope it helped
Answer:
C
Step-by-step explanation:
there is the ground line of about -5.5 to +5.5 = 11 ft.
then the 2 walls of 7 ft height = 14 ft.
that is already 25 ft.
the 2 roof sides are both a little bit longer than the corresponding ground line of 5.5ft.
so, estimated about 6ft per roof side. that adds 12 ft.
so, we are at about 37 ft.
and the closest answer is C. 36 ft.
in actual numbers a roof side is (using Pythagoras) :
roof side² = 2.5² + 5.5² = 6.25 + 30.25 = 36.5
roof side = 6.041522987... ft
so, the actual perimeter is
25 + 2×6.041522987... = 37.08304597... ft
