Answer:
Angles 2, 3 and 6,7 are acute angles
If x is the first number, x+2 is the next consecutive even integer. The difference (subtraction) of their squares equals 20. Therefore:
(x+2)²-x²=20...expand this:
x²+4x+4-x²=20
x²+4x+4-x²=20
4x+4=20
4x=16
x=4. Therefore the next consecutive even integer is x+2=6.
To check: 6²-4² must equal 20
36-16=20 check!
If 48 = 8 than 12 = x
to find x divide 48 by 8 which is 6. every 6 feet of fabric 1 blanket is made
so 12/6 equals 2
2 blankets can be made from 12 feet of fabric
The top one. they can't be expressed in a fraction or decimal
