2 (3a + 4)
first use the distributive property
6a + 8
then divide by 6 to get a by itself
6a/6 + 8/6
a = 1 1/3
Answer
7.53
1,227 then divide that by 163 so
1,227÷163= 7.53 so then you would go
163 and multiply 7.53 and you would get 1,227
Answer:
Pie= 3.14
Step-by-step explanation:
The enclosing boundary of a curved geometric figure, especially a circle.The circumference = π x the diameter of the circle (Pi multiplied by the diameter of the circle). Simply divide the circumference by π and you will have the length of the diameter. The diameter is just the radius times two, so divide the diameter by two and you will have the radius of the circle!
Answer:
the 29th element is copper
We know, Perimeter of a rectangle = 2(l + w)
2(6+x+2) = 2(3+2x+1)
2(8+x) = 2(4+2x)
16+2x = 8+4x
16-8 = 4x - 2x
8 = 2x
x = 4
Unknown lengths, x+2 = 4+2 = 6
2x+1 = 2(4)+1 = 8+1 = 9
2) We know, Area of a rectangle = a * b
2[7(x+1)] = 4(3x+6)
2[7x+7] = 12x+24
14x+14 = 12x+24
14x-12x = 24-14
2x = 10
x = 5
Lengths of unknown sides, x+1 = 5+1 = 6 cm
3x+6 = 3(5)+6 = 15+6 = 21 cm
Hope this helps!
