I'll teach you how to distribute −2x(−10x+1)

----------------------------------------------------

−2x(−10x+1)

Apply the distributive law:

Ex. of distributive law:

a(b+c)= ab+ac

-2x(-10x)+(-2x)*1

Apply minus/plus rule:

2*10xx-2*1*x

Simplify 2*10xx-2*1*x:

2*10xx= 20x^2

2*1*x= 2x

20x^2-2x

Your Answer Is 20x^2-2x

plz mark me as brainliest if this helped :)

Answer:

1.04p

Step-by-step explanation:

You will pay the whole price of the item which is p or 1p. Then you will add 4% tax or 0.04p. So the total will be 1p + 0.04p = 1.04p.

Answer:

Perimeter of the new box is 30.4 cm

Area of the new box is 57.76 cm²

Step-by-step explanation:

Jordan made a wooden square box, all sides of the wooden box are 6cm. If he wants to increase the length of all sides by 1.6, what will be perimeter and area of the new box?

From the question; all the side of the wooden box is 6 cm, if she increases all  side by 1.6, then the sides become; 6 cm + 1.6 cm = 7.6 cm

Since all the sides are 7.6 cm, then perimeter =  L + L + L + L

                                                                =7.6cm +7.6cm +7.6cm+7.6cm

                                                                  =30.4cm

or                                                          

perimeter of a square = 4L

                 = 4 × 7.6cm

                  = 30.4 cm

Therefore the perimeter of the new box is  30.4 cm

To find the area;

l = 7.6 cm

Area of a square = l × l

                           = 7.6 cm × 7.6 cm

                          =57.76 cm²

Therefore area of the new box is  57.76 cm²
