Correct option is third 
<h3><u>Solution:</u></h3>
Given that:
Need to check which of the expression from given four expressions will be true.
Let's first try to eliminate wrong options.
If we observe carefully, we can say that option 2 that is 
is not correct as 
must be equal to 
and not 
Lets now modify given expression that is:
On adding 1 to both sides we get
Hence correct option is third one that is
Answer:
35
Step-by-step explanation:
They are vertical angles which means angles opposite each other will be equal
<h3>
Answer: 112 square cm</h3>
=====================================
Work Shown:
area = base*height
area = 16*7
area = 112 square cm
----------------
Extra info (optional section):
The area formula for a parallelogram is the same as the formula for a rectangle. Imagine tilting a rectangle so that it's slanted. The area has not changed.
Or another thing to imagine is that let's say we had a stack of 2 by 4s. If the stack is perfectly vertical, aka forming a rectangle, then we can nudge the beams so that we can form a slanted parallelogram instead. Both configurations involve the same amount of wood, and therefore would lead to the same frontal surface area.
Answer:
xx=-0.8
Step-by-step explanation:
not sure if this is right because the 12xx is kind of strange
12xx+16-1=0
12xx+15=0
12xx=-15
12/12xx=12/-15
xx=-.8
Answer:
The answer is 6 and -6
Step-by-step explanation:
The given equation is
where a = 1. b = -k, c = a
since the equation (1) has equal roots
Hence volume of k = 6, -6
