Your answer should be 93 because 7 times 7.5 is 52.5 and 9 times 4.5 is 40.5 40.5+52.5=93!
The answer is x>13. First you must simplify both sides of the inequality. Which is now 4x +8>60. Then you must subtract 8 from both sides and finally divide both sides by 4.
4x + 8 -8> 60 - 8
4x>52
4 divided by 52 is 13. The final answer is x>13.
Answer:
Step-by-step explanation:
Find the area of each shape, then multiply by 20, then round to nearest hundred.
Half circle:
=πr²/2
=50π
=157.08
Large square:
=L•w
=20(22)
=440
Small square:
=L(w)
=12(3)
=36
Triangle:
=b(h)/2
=8(3)/2
=12
Btu req:
=(157.08+440+36+12)(20)
=(645.08)(20)
=12901.6
=12900 BTU
Exact form -9/20 or in decimal form is -0.45
Answer:
D - (-2)^2 does not equal to -4
Step-by-step explanation:
√-4 does not equal -2 because if you try squaring -2 you will get 4 not -4, because 2 negative number makes it a positive.
For example
-2 x -2 - There are two negative numbers, so it should equal...
4
