We use the negative exponent rule to change an expression with a negative exponent to an equivalent expression with a positive exponent. The rule states that any nonzero number raised to a negative power equals its reciprocal raised to the opposite positive power.

What is the product (9t-4)(-9t -4)

r-ruslan [8.4K]

Hey Tro2,

Lets find the product of your equation together,

The question we are encountering is : What is the product (9t-4)(-9t-4)?

Lets simplify this step by step, shall we.

$\left(9t-4\right)\left(-9t-4\right)$ : Equation

$\mathrm{Distribute\:parentheses\:using}:\quad \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd$ .

Where : $a=9t,\:b=-4,\:c=-9t,\:d=-4$ .

This leads to $9t\left(-9t\right)+9t\left(-4\right)-4\left(-9t\right)-4\left(-4\right)$ .

Now we have to $\mathrm{Apply\:minus-plus\:rules}$ .

Where: $-\left(-a\right)=a,\:\:\:\:+\left(-a\right)=-a$

$-9t\cdot \:9t-9t\cdot \:4+4\cdot \:9t+4\cdot \:4$

$=-81t^2+16$

Find the flaw with the following "proof" that every postage of 3 cents or more can be formed using just 3-cent and 4-cent stamps

Reika [66]

Answer:

The main flaw of this proof is that it did not take into consideration the fact a 4 cent postage must be made with a 4 cent stamp and a 3 cent postage must be made with a 3 cent stamp but only looked at allocating the stamps based on the total amount of postage

Step-by-step explanation:

From the question we are told that

The proof is

Every postage stamp of three cents or more can be formed using just 3 cent and 4 cent stamps.

Basic Step : We can form postage of 3 cents with a single 3 cent stamp and we can form postage of 4 cents using a single four cents tamp

Inductive Step: Assume that we can form postage of j cents for all non negative integers j with j <= k using just 3 cent and 4-cent stamps. We can then form postage of k+1 cents by replacing one 3 cent stamp with a 4-cent or two 4-cent stamps with three 3-cent stamps

FLAW IDENTIFICATION

Looking the inductive step, the statement ''by replacing one 3 cent stamp with a 4-cent or two 4-cent stamps with three 3-cent stamps '' means that it is possible to use a 3-cent stamp for postage that requires a 4 -cent stamp and this is not correct according the statement in the basic step

Generally the main flaw of this proof is that it did not take into consideration the fact a 4 cent postage must be made with a 4 cent stamp and a 3 cent postage must be made with a 3 cent stamp but only looked at allocating the stamps based on the total amount of postage

Pre ap geometry, please help with number 11.

arlik [135]

Perimeter is the sum of all three sides so in this case x+(3x+2)+(3x+2).
They also gave us the perimeter which is 39 so
39= x+(3x+2)+(3x+2)
Simplify so 39=7x+4. [x+3x+3x=7x and 2+2=4]
Then get x by itself so subtract 4 from both sides.
35=7x
Then divide both sides by 7 to get x by itself.
Which leaves us with
X=5
