Answer:
Fill in the blanks to make the following statements true. Also named the property used.
a. (-5) + (-4) = ___ + (-5),
b. 4 + __ = 4,
c. - 53 + ___ = - 53,
d. 4 + [(-5) + (7)] = [4 + (7)] + ___,
e. 25 + [(-50) + 5 ] = (25 + 5) + ___,
f. (-4) + ___ = -4,
g. 4 + (-4) = ___,
h. 5 + ___ = 0 ,
Step-by-step explanation:
Fill in the blanks to make the following statements true. Also named the property used.
a. (-5) + (-4) = ___ + (-5),
b. 4 + __ = 4,
c. - 53 + ___ = - 53,
d. 4 + [(-5) + (7)] = [4 + (7)] + ___,
e. 25 + [(-50) + 5 ] = (25 + 5) + ___,
f. (-4) + ___ = -4,
g. 4 + (-4) = ___,
h. 5 + ___ = 0 ,
F+g(x) = f(x) + g(x) = 3x-1 + x+2 = 4x+1
If we are looking to simplify two trinomials, it is easiest to put them on top of each other and subtract.
7x² - 2x + 5 7x² - 2x + 5
- (3x² + 4x + 10) -3x² - 4x - 10
4x² - 6x - 5
The volume is about 7234.56 cubic mm.
I assume the radius is 12 mm, it must have been repeated accidentally.
To find the volume of a sphere, we cube the radius, multiply by pi and finally multiply by 4/3.
We are the steps:
(12^3) = 1728 x pi (3.14) = 5425.92 x (4/3) = 7234.56
