For questions 9&10 you will just have to graph it on the graph. Hopefully I helped you tho.
Answer:
Below in bold
Step-by-step explanation:
I AM ASSUMING that CDEF is a Rhombus.
If it is than triangle DEG is right-angled.
so 2x + 18 + 5x + 2 = 90.
7x = 90 - 20 = 70
x = 7.
So m < CDF = 5x + 2
= 5(10) + 2
= 52 degrees.
m < DCE = 2(10) + 18 = 38 degrees.
The diagonal bisects < DCF so m < ECF = 38 degrees.
So m < DCF = 2 * 38 = 76 degrees.
Opposite angles of a rhombus are equal so m < DEF = 76 degrees.
Answer:
-3x
Step-by-step explanation:
:)
(3s^13)(9s^-5) is simply a matter of multiplication.
First, multiply the coefficients, or the numbers in front of the s. In this case, 3s x 9s = 27s.
When multiplying exponents, you simply add them, so the next step is 13-5 or 8. Therefore your answer is 27s^8
It will get smaller unless the term is lower than negative 1
