First or the second idk what the red filling is supposed to be...
So first you would need to FOIL the problem (first-outer-inner-last) so you would multiply x by x and get {x²} then you would multiply x by 1 so you would get just plain {x} then multiply 2 by x so to get {2x} then multiply the last terms 2 and 1 together to get {2} so then put it all together = x² + x + 2x + 2 then you add like terms together so you end up with = x² + 3x + 2 as the answer
Answer:
29
Step-by-step explanation:
Substitute the values for the variables in the expression.
(9) + 4(5)
9 + 20

52°C is equal to 125.6 degrees Fahrenheit.
Given that 52°C it should be converted into degrees of Fahrenheit.
The celcius is represented by the letter C
And the degree Fahrenheit is represented by F
The formulas for the conversion are given by
and
Here the given is 52°C and we convert this to Fahrenheit by using the formula
We have a C value is 52
By substituting the C value in the formula we get the F value
Hence 52°C to degrees Fahrenheit is 125.6
