The length of a rectangle is 3 times its width. The perimeter is 39. Find the length and width of the rectangle.​
nata0808 [166]

Answer:

Let width of rectangle be x cm.

3x+x+3x+x=39

8x=39

x=39÷8

=39/8

=4/7/8

3x=39/8×3

=117/8

=14/5/8

Hence, length=14/5/8cm while width=4/7/8cm.

I NEED HELP PLEASE. LOOK AT PICTURE
Bond [772]

Answer:

Part 1) \frac{a^4}{4b^2}

Part 2) -\frac{v^9}{w^6}

Step-by-step explanation:

we know that

When divide exponents (or powers) with the same base, subtract the exponents

Part 1) we have

\frac{3a^{2}b^{-4}}{12a^{-2}b^{-2}}=(\frac{3}{12})(a^{2+2})(b^{-4+2} )=\frac{1}{4}a^{4}b^{-2}=\frac{a^4}{4b^2}

Part 2) we have

\frac{v^3w^{-3}}{-v^{-6} w^3} =-v^{3+6}w^{-3-3}=-v^9w^{-6}=-\frac{v^9}{w^6}
