Dividing 4x by 4 isolates x on one side of the equation
Answer: 253°F
Step-by-step explanation:
Given the following :
Temperature in Antarctica = - 121 Fahrenheit
Temperature in Sahara desert = 132 Fahrenheit
Number of degrees in which Sahara desert is warmer than Antarctica :
(temperature in Sahara desert - temperature in Antarctica)
= ( 132°F - (-121°F))
= (132°F + 121°F)
= 253°F
Sahara Desert is 253°F warmer
According to the law of sines:

Using the given values, we can find the angle B and find the number of possible triangles that can be formed.

The range of sin is from -1 to 1. The above expression does not yield any possible value of B, as sin of no angle can be equal to 1.45.
Therefore, we can conclude that no triangle exists with the given conditions.
Answer:
x>=35
Step-by-step explanation:
-4(x+10)>= -7x + 65
-4x-40>= -7x+65
-4x+7x>=65+40
3x>=105
x>=105/3
x>=35
9. Area of a triangle is proportional to height. If the height increases by a factor of 4, then ...
The area will increase by a factor of 4. . . . . (2nd selection)
10. The base lengths and height are needed:
• 5 mm
• 8 mm
• 10 mm
