Answer:
D
Step-by-step explanation:
Given
- (x + 3) - 2(4x - 3) ← distribute both parenthesis
step 1
= - x - 3 - 8x + 6 ← collect like terms
step 2
= - 9x + 3
To find out the answer of the two multiplied products with the help of partial products we separate into unit based numbers so as to, for easier calculation and simplification with units of zeroes. So, in this case we are given the product of 4 times of 652.
Here we need to expand this product of higher number to zeroes and take aside the added numbers to come back to the original multiple of a product. That is:
We just separated and expanded the product to be multiplied by removing other units following it. Same goes for other units at Hundredth, tenth and unitary position.
Therefore,
For tenth term.
The terms after splitting and expanding the product before multiplication is:
Multiply the product elements in individual manner and add the elements forged by individual multiplication to get the required solution.
Hope it helps.
Answer:
△ABC is first reflected across the line y=x, then reflected across the x-axis. Since the transformations are rigid, △ABC ≅ △A''B''C''.
Step-by-step explanation:
Comparing △ABC and △A'B'C', we see that the x- and y-coordinates have been switched. This describes a reflection across the line y=x.
Comparing △A'B'C' and △A''B''C'', we see that the y-coordinates have been negated. This describes a reflection across the x-axis.
Reflections are called rigid transformations. This is because they preserve congruence and shape. Since congruence is preserved, △ABC ≅ △A''B''C''.
