Answer:
Step-by-step explanation:
Consider the provided number.
We need to find the approximate value of 
to the nearest hundredth.
First find two perfect squares that the irrational number falls between.
118 is lying between 100 and 121, therefore the square root value of 118 will be somewhere between 10 and 11.
118 is closer to 121 as compare to 100.
Therefore,
Consider the number 
First find two perfect squares that the irrational number falls between.
319 is lying between 289 and 324, therefore the square root value of 319 will be somewhere between 17 and 18.
319 is closer to 324 as compare to 289.
Therefore,
The answer is F because you use the square's measurements as the base of each triangle then multiply each triangle then divide by 2. The multiply by 4 because there are four triangles and multiply 12 by 12 to get 144 because it is the base and the height of the square.
Answer: 78°
Step-by-step explanation:
Looking at the picture, we can tell that ∠ACD and ∠DCB are supplementary angles. This means, they are equal to 180°. With that, we can find x and plug it into ∠DCB.
4x+2+3x+3=180 [combine like terms]
7x+5=180 [subtract both sides by 5]
7x=175 [divide both sides by 7]
x=25
Now that we know x=25, we can plug it in to find ∠DCB.
3(25)+3 [multiply]
75+3 [add]
78
Now, we know ∠DCB is 78°.
The answer is D. 18 + (–14) = –14 + 18
