One morning the temperature was-5°f. by noon it had increased by 12 degrees. what was the temperature at noon? explain your answer.

Let's write this as an equation.

In this case, represents the temperature at noon.

To solve this, we simply need to add . We can also rearrange the terms to make a simpler equation.

All we need to do is find .

Step-by-step explanation:

We are given that one morning the temperature was

By noon it had  increased by 12 degrees.

We have to find the temperature at noon and explain.

Temperature at morning=-5 degrees Fahrenheit

Temperature increased by =12 degrees

Therefore, the temperature at noon=12+(-5)=7 degrees Fahrenheit

Because temperature is increased by 12 degree therefore, 12 added to -5 degrees Fahrenheit to find the value of temperature at noon.

Sign of larger number is positive therefore, the sign of sum will be positive.

Hence, the temperature at noon=

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
