you just have to foil it.
hope i help
1) Nearest thousand: 457,000 (Look at the thousandths place. Is the number closer to 457,000 or 456,000?)
Hundred: 457,000 (Look at the hundredths place. Is the number closer to 456,000 or 457,000?)
Ten: 456,990 (Look at the tenths place. Is the number closer to 456,980 or 456,990?)
2) The value of the expression when x=6 is 27. Explanation:
6x-7
6(6)-7

27
The value of the expression when x=3 is 11
Explanation:
6x-7
6(3)-7
18-7
11
Let b>a
We are told that b=a+6 and that a+b=30
Using the value of b=a+6 in a+b=30 gives you:
a+(a+6)=30 combining like terms on left side
2a+6=30 subtract 6 from both sides
2a=24 divide both sides by 2
a=12, and since b=a+6
b=18
So the two numbers are 12 and 18.
SAS (Side-Angle-Side): If two pairs of sides of two triangles are equal in length, and the included angles are equal in measurement, then the triangles are congruent. SSS (Side-Side-Side): If three pairs of sides of two triangles are equal in length, then the triangles are congruent.
