Answer:

should be 66.4

Step-by-step explanation:

triangular prism:

Using the formulas

AB=s(s﹣a)(s﹣b)(s﹣c)

V=ABh

s=a+b+c

Solving forV

V=1

4h﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=1

4·3·﹣24+2·(2·2)2+2·(2·2)2﹣24+2·(2·2)2﹣24≈5.19615

5.2 · 2 = 10.4

Rectangular prism:

V=whl=2·2·14=56

10.4+56=66.4

The Federal Reserve Bank is responsible for minting new coins. True or false

andriy [413]

That's false. Coinage is the responsibility of the US mint.
That's why the process is called "minting" and not "reserving".

Determine whether 8x + 18 + x is equivalent to 9(2+x) Complete the sentence to justify your answer

AlekseyPX

Answer:

Yes they are equivalent

Step-by-step explanation:

8x + 18 + x = 9x + 18

9(2+x) = 18 + 9x = 9x + 18

Therefore, 8x + 18 + x is equivalent to 9(2+x)

write an equation in point-point form for the line through the given point with the givedescribe how the graph of y | x| -4 is l

Digiron [165]

a) The point-slope form of the equation of a line through point (h, k) with slope m is
y - k = m(x - h)

In point-slope form, the equation of the line through (-3, -7) with slope -6/5 is
y + 7 = (-6/5)(x + 3)

b) The graph of
y = |x|-4
represents a translation downward 4 units of the graph of
y = |x|
It retains the same general shape and axis of symmetry, but will have two (2) x-intercepts instead of one (1).
