Step 1.)
7x + 7 * 4.
We need to expand this term by multiplying a term and an expression.
The following product distributive property will be used:
A(B+C) = AB + AC
Numerical factors in this term have been multiplied.
In our example, the resulting expression will consist of 2 terms:
the first term is a product of 7 and x
the second term is a product of 7 and 4.
7x + (7 * 4)
Numerical factors in this term have been multiplied.
Which equals:
7x + 28
Hope you understand this and it helps. Have a great evening!
Answer:
30cm
Step-by-step explanation:
"5 or above, give it shove. 4 or below, let it go." The number is the tenth's place is 2(since this isn't a decimal), and you need to round it by the number to it's right: which is 8. Since 8 is greater than 5, you change the 2 to a 3 and the 8 becomes a 0.
Well, 9 billion = 9,000,000,000 so in scientific form it would be 9 x 10^9 To get the exponent, just count the number of zeros, which for 9 billion we have 9
Answer:
R' = (-2, -3)
Step-by-step explanation:
When a figure undergoes a 180degree rotation, both the (x) and (y) coordinates are multiplied by (-1). The coordinates of the given point are (2, 3). Multiply both of these numbers to fine (R'), that is point (R) after it undergoes its rotation. The coordinates of (R') are (-2, -3).
