To get a single h, all you have to do is divide everything by 4
so h =
Answer:
x=√−16n−28 or x=−√−16n−28
Step-by-step explanation:
Step 1: Add -16n to both sides.
x2+16n+28+−16n=0+−16n
x2+28=−16n
Step 2: Add -28 to both sides.
x2+28+−28=−16n+−28
x2=−16n−28
Step 3: Take square root.
x=√−16n−28 or x=−√−16n−28
You can write it either way.
75 B because there’s a difference of 25 in each temperature interval
X raised to the power of two" or equivalently "x squared" (which is x mulitplied by itself). In fact, if we multiply the variable x by itself a number of times (say n - times) we get: xn. The number represented here as x is called the base, and n is called the power or exponent.
