Step-by-step explanation:
LxB
8x7
equals :56
Area equals to 56cm
Y= 3( x -2 )² - ( x-5 )² = 3 ( x² - 4 x + 4 ) - ( x² - 10 x + 25 ) =
= 3 x² - 12 x + 12 - x² + 10 x - 25=
= 2 x² - 2 x - 13 =
= 2 ( x² - x + 1/4 - 1/4 ) - 13 =
= 2 ( x - 1/2 )² - 1/2 - 26/2 = 2 ( x - 1/2 )² - 27/2
Answer: D)
Answer: F
Step-by-step explanation:
This is basically like 2 rectangles. Find the area of both and add them together.
Remember that the area is
x
.
Area of Rectangle 1:
= 7,
= 14
14 x 7 = 98
Area of Rectangle 2:
= 5,
= 14
14 x 5 = 70
Add the areas together: 98
+ 70
= 168

<em>Write any 4 laws, or properties, of exponents.</em>

When we multiply together numbers with the same base,
we add the exponents.



When we divide numbers with the same base, we
subtract the exponents.



If we have a fraction to a power, we raise the numerator and
the denominator to that power.
And then last but not least,



If we have a number with a negative exponent, we flip it over.
