Answer:

<h2>1.5 cm²</h2>

Step-by-step explanation:

Substitute <em>a = 0.5 cm</em> to the formula <em>SA = 6a² </em>:

<em>SA = 6(0.5)² = 6(0.5 · 0.5) = 6(0.25) = 1.5 cm²</em>

a = edge length = 0.5 cm

S = surface area of cube

S = 6*a^2

S = 6*(0.5)^2

S = 6*0.25

S = 1.5

<h3>The surface area of the cube is 1.5 square cm</h3>

You can use cm^2 in place of "square cm" to mean the same thing.

Express the trig ratios as fractions in simplest terms.
Neporo4naja [7]

Answer:

See below

Step-by-step explanation:

\cos M=\frac{adjacent}{hypotenuse}=\frac{56}{70}=\frac{4}{5}\\\\\sin L=\frac{opposite}{hypotenuse}=\frac{56}{70}=\frac{4}{5}

Hence, both ratios are equal to each other

Rewrite 8x - 7 as the product of two factors
kykrilka [37]

Answer:

factors are any group of number or expressions which, when multiplied, produce another number or expression.

Basic example:  4 can be broken into 2 factors---2 and 2.  2 times 2 = 4

Example using an unknown:

2X + 6 = 2 * (X + 3)

In the given problem, there is no whole-number common factor.  A normal convention would be to factor based on the unknown term----thus 8X is factored into 8 and X.

So:  8X + 7 = 8 ( X + 7/8 )

The following would also be correct:

8X + 7 = 4 ( 2X + 7/4 )

Step-by-step explanation:
