Combine like terms to solve the equation
you can use formular method or factorisation but formular method is easy and convinient
1. One face is 5.1*2.5=12.75 un^2, one is 8.5*2.5=21.25, one is 6.8*2.5=17, and two are 1/2*6.8*5.1, so both are 34.68. Total is 85.68, rounded to 85.7 cm^2. (C)
2. The area of the circles is 2(π*2^2), which is about 25.1. The rectangle's area can be found as 2π*2*3, which is about 37.7. The total is rounded to 62.8 m^2 (D)
3. Rectangular faces: 3.6*1.8=6.48, 8.5*1.8=15.3, 7.7*1.8=13.86
Triangles: 2(1/2(3.6*7.7))=27.72
Total: 63.36, round to 63.4 km^2 (B)
For every x value, there should be only one y value. Or, for every input there is only one output.
A - Incorrect - there are two 2's for the x values and each of them has a different y value
B - Correct - all of the x values are different and all of the y values are different
C - Incorrect - there are two 11's for the x values and each of them has a different y value
D - Incorrect - there are two 3's for the x values and each of them has a different y value
Hope this helps! :)
Answer: His temperature is 99°F
Step-by-step explanation:
Let's state what we know:
Steve's temperature was initially 102°F
Later it dropped 3°F lower
Since his temperature decreased we need to subtract 3 from 102 to see what his temperature is now
102-3=99
