Answer: B: They have different perimeters but the same area.
Explanation:
For the rectangle on top, the perimeter (the lengths of all the sides added together) is 5+4+5+4=18. The area (the length of the base times the length of the height) = 5*4=20.
For the larger rectangle on the bottom, the perimeter would be 10+2+10+2=24. The area of this rectangle would be 10*2=20.
The two rectangles have the same area (20) but not the same perimeter.
Answer:
She would have 33 more pages left.
Step-by-step explanation:
You would want to subtract 23 from 56.
Triangle inequality rule states that the sum of eachpair of sides must be greater than the third sides.
240 + 123 > 207 true
240 + 207 > 123 true
123 + 207 > 240 true
A = √(s(s-a)(s-b)(s-c))
s is the semi-perimeter (a + b + c)/2
s = (240 + 123 + 207)/2
s = 285
A = √(285*(285-249)(285-123)(285-207))
A = 12,730 units^2
Use the distributive property to multiply 1/5 by 4-3x.
Multiply 1/5 and 4 to get 4/5.
Multiply 1/5 and -3 to get -3/5.
Use the distributive property to multiply 1/7 by 3x-4.
Multiply 1/7 and 3 to get 3/7 & 1/7 × -4 to get -4/7.
Subtract 
from both sides.
Combine 
and 
to get 
.
Subtract 4/5 from both sides.
The least common multiple of 7 and 5 is 35. Convert -4/7 and 4/5 to fractions with denominator 35.
Because 
and 
have the same denominator, subtract them by subtracting their numerators.
Subtract 28 from -20 to get -48.
Multiply both sides by 
, the reciprocal of 
.
Multiply 
by by multiplying the numerator by the numerator and the denominator by the denominator.

Reduce the fraction 1680/1260 to its lowest terms by extracting and cancelling out 420.
Its basically just subtracting from one another
for example, 6-6 is 6
or -4-3= 7
