Answer:
Step-by-step explanation:
The right option es a)
because the general form is:
ax^2+bx+c
so you can easyly identify b=-5
Answer:
80 degrees
Step-by-step explanation:
The whole angle EBD is 115 degrees, and angle DBG is 35 degrees, therefore
angle GBE is 115-35=80 degrees
Think about it like this, DBG and GBE need to add up to the angle measure of EBD, in other words 35 + GBE = 115
Answer:
(a)
In this question, you can simply just multiply the exponent of 2 and the exponent of 5, in order to get a power of 10.
(b)
For this question, we need to organize the numbers as a fraction
We need to subtract the exponents from each variable. In
and y, we need to subtract 3-1 to get
. In
and
, we need to subtract 7-3 to get
. Now, we can divide 12 and 6 normally to get 2. So, the answer would be
.
Using:

Substituting x= 5 from given question, we get answer:
C) 5
2.61 x 10^11 would be the correct answer
