Answer: 6 inches long and 4 inches wide

Step-by-step explanation: The dimensions of the actual crate are 20 times those on Jacob's drawing. The dimensions on the builder's drawing are 1/10 of those, so (1/10)(20) = 2 times the dimensions on Jacob's drawing.

hope this helps

Answer:

\large\boxed{\dfrac{1}{x^2}+x^2=23}

Step-by-step explanation:

\left(\dfrac{1}{x}+x\right)^2=25\qquad\text{use}\ (a+b)^2=a^2+2ab+b^2\\\\\left(\dfrac{1}{x}\right)^2+2(x\!\!\!\!\diagup)\left(\dfrac{1}{x\!\!\!\!\diagup}\right)+x^2=25\\\\\dfrac{1}{x^2}+2+x^2=25\qquad\text{subtract 2 from both sides}\\\\\dfrac{1}{x^2}+x^2=23

So like tell me the answer I think it’s like either 3 or 6a^9 but I’m not sure
Iteru [2.4K]

I'm not sure what you mean by 3 or 6a^9, since there are only variables in the photo, but we can try breaking it down.

Let's start with the bottom,

a^2 * a^3 would be a^5 because for exponents you add the exponents of what's multiplied (product rule)

Then using the quotient rule, where you subtract the exponents, a^5/a^5 = a^(5-5)

And anything to the 0th power is 1, so your answer should be 1

Hope that helps!
