Answer:
the answer is C 6x2 .....................
Answer:
x ≈ 13.5
Step-by-step explanation:
Using the sine rule in the triangle, then
=
( cross- multiply )
x × sin27° = 11 × sin34° ( divide both sides by sin27° )
x =
≈ 13.5 ( to the nearest tenth )
Area of a square:
A= side^2
= (6x + 1) ^2
=<u> 36x^2 + 12x + 1 feet^2</u>
Answer:
C) (a-12b)(a+12b)
Step-by-step explanation:
a^2-144b^2 = (a-12b)(a+12b)
This is the formula that when two terms squared are written with a minus sign between them their factors are the product of the original numbers once with a plus sign and once with the minus sign.
This can be explained by multiplying them.
(a-12b)
<u> *(a+12b) </u>
a²- 12ab
<u> +12ab - 144b² </u>
<u> a² +0 - 144b² </u>
We see we get the same answer as applying the formula above.
If you have a whole number move the number of exponents in 10 and move left. If you have a decimal, and the 10 is negative exponent, move to the write.
