Answer:
-20
Step-by-step explanation:
(-4) × [ (8) + (-3)]
(-4) × [ (8-3)]
(-4) × [5]
-20
Answer:
It is +2 or since (+2)*(+2 ) gives. If you think that it would be (-2) also then you are wrong because root of a positive rational number is always positive number.
Step-by-step explanation:
Let the square root of four be ‘k’.
Then we have
(4)^1/2=k
(Squaring both sides)
4=(k)^2
=>(k)^2–4=0
=>(k)^2-(2)^2=0
=>[k+2][k-2]=0 {since (a)^2-(b)^2=(a+b)(a-b)}
if product of two numbers is 0 then either of one must be zero.
If k+2=0 then k=-2
If k-2=0 then k=2
From here we got two answers but -2 should be omitted because when we square an equation we add “root extra”which means that when we square an equation one root is added.
It would be the first one.
I converted each equation into the form y =\<\> Mx+b to find the slope and y intercept.
We know that the slope will be positive since the line is positive linear. We also know that the y intercept is 3, since the line crosses the y axis at 3.
Since the shaded part is above the line, the sign used will be this one: >
So therefore it’s the first one....
Answer:
B
Step-by-step explanation:
4 represents the number of bounces
and 1/2 represents the decreases in the height of bounce
HAVE A GREAT DAY!
Side lengths with <span>4 in, 8 in, 3 in.</span> will not form a triangle 'cause we know, that sum of shorter sides must be greater than the longer side but here it's not.
In short, Your Answer would be Option D
Hope this helps!
