Answer:
x = ±11/4
Step-by-step explanation:
Rewrite -16x^2+121=0 as 16x^2 - 121=0 and then as 16x^2 = 121.
Take the square root of both sides. This returns 4x = ±11, and so:
x = ±11/4
<span>Which of the following inequalities is correct?
-9 ≥ -7 is wrong as 9>7 but -9 < -7
-10 > |-10| is wrong as </span>|-10|= 10<span>
6 ≤ |-6| is right cause </span>|-6| =6 and we have 6=6 or <span>6 ≤ |-6| is also right</span><span>
0 < -13 is totally wrong

Answer:
The expression 7x represents the height of the container.
Step-by-step explanation:
From the question:
We are being informed that; if the length of the container is half of a foot longer than its width.
Let the width be x;
Then the length of the container can now be ; x+1/2
We all known that the volume of a rectangular prism is : V= l×w×h
here;
l = length
w = width
h = height
If we rewrite the given expression :
;
Then we factor we make a similar coefficient of the above equation, the remaining entities left in the parenthesis should be a linear term with a leading coefficient of 1 to match the expression for the length of the container.
i.e
Hence, if the length of the container is half a foot longer than its width, x, then the expression 7x represents the height of the container.
