Answer:

−4304

Step-by-step explanation:

1. The given determinant is :

\begin{vmatrix}7 &31 \\  142& 14\end{vmatrix}

We need to find its determinant . It can be solved as follows :

\begin{vmatrix}7 &31 \\  142& 14\end{vmatrix}=7(14)-142(31)\\\\=-4304

So, the value of determinant is equal to −4304.

Factorize 9(a+1)^2-81​
lora16 [44]

Answer:

The answer is 9(a-2)(a+4).

Step-by-step explanation:

Use a^{2} -b^{2} =(a-b)(a+b)  

9(a+1)^{2} -81= 9( (a+1)^{2}-9)=  9( (a+1)^{2}-3^{2} )= 9(a+1-3)(a+1+3)\\=9(a-2)(a+4).

A rectangle is divided into equal squares. One row covers 1/8 of the whole rectangle. There are 3 squares in each row. How many
LenaWriter [7]

Answer:

There are 24 squares in the entire rectangle

Step-by-step explanation:

Trom the problem, we are given that one row covers 1/8 of the entire rectangle.

We are also told that this one row, contains three squares.

In other words, what this means is that three squares cover 1/8 of the entire rectangle.

The question is now if three squares cover only 1/8 of the rectangle, how many squares cover the whole rectangle.

In fraction, we can represent a whole using 1/1

We can set up a simple relation to this effect.

3 squares give 1/8 of the rectangle

x squares give 1/1 of the rectangle

cross multiplying, we have

x = 3 ÷(1/8) = 24

Therefore, there are 24 squares in the entire rectangle
