What expression is equivalent to the area of metal sheet required to make this square-shaped traffic sign?

AveGali [126]

Answer: $\text{Area of the square shaped traffic sign }=16x^2+9+24x$

Step-by-step explanation:

Given: The side of the square shaped traffic sign = 4x+3

We know that the area of square is given by:-

$Area= side^2$

Therefore, the area of the side of the square shaped field is given by:-

$Area=(4x+3)^2$

We know that , $(a+b)^2=a^2+b^2+2ab$

Therefore,

$(4x+3)^2=(4x)^2+(3)^2+2(4x)(3)\\=16x^2+9+24x$

Hence, $\text{Area of the square shaped traffic sign }=16x^2+9+24x$

Using property find a.3/5×-2/7+4/5-3/10×2/7

Sedaia [141]

Here the answer is 19/35

Step-by-step explanation:

$\frac{3}{5} X\frac{-2}{7} +\frac{4}{5}-\frac{3}{10} X\frac{2}{7}$

We will apply BODMAS rule

In this rule multiplication comes before add and subtraction

= $\frac{-6}{35} + \frac{4}{5} - \frac{3}{35}$

= $\frac{4}{5} - ( \frac{6}{35}+ \frac{3}{35})$

= $\frac{4}{5} - \frac{9}{35}$

= $\frac{4 X 7}{5 X 7} -\frac{9}{35}$

= $\frac{28}{35} - \frac{9}{35}$

= $\frac{19}{35}$
