Answer:
C. 249
Step-by-step explanation:
it’s a 3 digit number
9 is ones
4 is one tenth
a. Dilation of 2nd equation by a factor of 12
b. The systems have the same solution, as dilations do not affect overall coordinates, changing side lengths but not angles
Answer:
A cylinder with height 4 units and radius 4 units
Step-by-step explanation:
Given that The coordinates A (0, 0), B (0, 4), C (4, 4), and D (4, 0) are graphed and connected together.
Since AB =BC=CD=DA we get all sides are equal
Also AB is y axis and AD is x axis, hence one angle is 90 hence all angles are 90 degrees.
Hence this is a square
When it is rotated about y axis, we gt a cylinder which has radius equal to side of the square and height also equal to the side of the square.
Answer:
A. and C.
Step-by-step explanation:
Identify carefully!
Factor:
Solution: a^2 + ac + ba + bc ========>Answer: (a + b)(a + c)
Factor:
a^2 + ac + ba + bc
a^2 + ab + ac + bc
=(a + b)(a + c)
Answer: =======> (a + b)(a + c)
Hope that helps!!!! : )
