Mathematics

Answer:

x =  8.7 or x = 1.3

Step-by-step explanation:

x² – 6x= 5

(b/2)² = (6/2)² = 9 (Using Completing the square method)

x² – 6x + 9 = 5 + 9

(x -5)² = 14

x-5 = √14

x-5 = ±3.7

Either x-5 =3.7 or x-5 = -3.7

x = 3.7+5 or x = -3.7+5

x =  8.7 or x = 1.3

Find the volume of the composite figure. please!
Irina-Kira [14]
Volume= Length * width ( aka Base ) * height 

Break up the figure into easier figures, a small square and a bigger square.

Small square- 3*2*1 = 6 cm

Large Square- 7*6*1 = 42 cm

42 + 6 = 48 cm. But wait! You have to take one more step, which is minus-ing 6 from 48. Why? Notice that there is a little area where a side of the small square meets the bigger square. That little area is worth 3 cm ( length is 3, height is 1 cm ) times 2 ( 3 cm is one side, another 3 cm is the other side from the other square ) = 6 cm.

Your total answer should be 42. ( or 48, if your teacher doesn't count the area where the squares meet/join together ).
