Calculate The Length Of The Side BC. Using Pythagoras

Answers

Answer 1

Answer:

10m

Step-by-step explanation:

A^2+B^2=C^2

6^2+8^2=C^2

36+64=C^2

100=C^2

10=C

Answer 2
It’s 10m. If you know about Pythagorean triples, one of the triplets is 6,8,10. The other way is the Pythagorean Theron which is a^2 +b^2=c^2. So if we plug it in it would be 6m^2+8m ^2=am^2. So 6m^2+8m ^2 would be equal to 100m^2. Then you would have to find the square root of it to get 10m.

Reagan has a rectangular bedspread that measures 238 centimeters by 435 centimeters. She wants to sew a fringe around the edge of the bedspread. WHAT LENGTH OF FRINGE DOES REAGAN NEED TO USE?

Answers

Answer: 1346cm

Step-by-step explanation:

From the question, we are informed that Reagan has a rectangular bedspread that measures 238 centimeters by 435 centimeters and that he wants to sew a fringe around the edge of the bedspread.

This simply means that we have to find the perimeter of the rectangular bedspread and this will be:

= 2(length + width)

= 2(435 + 238

= 2(673)

= 1346cm

3x2−13

9x2−24x+19

9x2−24x+13

Answers

Answer:

9x^2  -24x +13

Step-by-step explanation:

(g º f)(x) = g(f(x))

g(f(x)) = (3x-4)^2 - 3

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

g(f(x)) = 9x^2 - 24x + 16 - 3

g(f(x)) = 9x^2  -24x +13
