Mathematics
1 answer:
mote1985 [20]3 years ago
8 0

Answer:

C. as t^2+t +t =t^4  + 9^2-3+3=9^2 = t^3 - 81 we are forced to -81 as we would be required to move t^3 first to the other side before  -81 therefore if t is a perfect square of 4 and 9 is a perfect square too we can use. Since both terms are perfect squares, factor using the difference of squares formula,

a2−b2=(a+b)(a−b)where a=xand b=9.(x+9)(x−9)

Step-by-step explanation:

Sveta_85 [38]

Answer:

4.5

Step-by-step explanation:

In order to find the answer to this question you will first need to convert Lincolns height into a improper fraction and then convert the improper fraction into a decimal number.

L =4\frac{5}{10}

Convert into improper fraction

4\frac{5}{10} =10 \times4=40+5=45=\frac{45}{10}

Convert into decimal by dividing the numerator by the denominator:

45\div10=4.5

L=4.5

Hope this helps.

Which of these is not a method to solve systems of
Allushta [10]

Answer:

Fourth option

Step-by-step explanation:

The answer is the fourth option "difference of squares method." It's not the first option because the substitution method is when you pick one of the equation in a system of equations, solve it for a variable and then plug the variable into the other equation to help solve. It's not the second option because the graphing method is used to solve a system of equations by graphing the equations on the same coordinate plane, it's not the third option because the addition method is also known as the elimination method which is the third method to solving a system of equations. Therefore your answer is the fourth option.

Hope this helps.

then we do the right needed inverse to move the variables all to one side and the other numbers to another... this is a way we simplify expressions

Hope this helps :)
