Answer: The three sides are 15 cm, 25 cm, 30 cm

=====================================================

Explanation:

Let x be some positive real number

The sides are in ratio 3:5:6 which means we can multiply all three sides by x getting 3x:5x:6x

The sides of the triangle are 3x, 5x and 6x. The sides add up to the perimeter 70

3x+5x+6x = 70

14x = 70

x = 70/14

x = 5

With this x value, we can find the three sides

3x = 3*5 = 15
5x = 5*5 = 25
6x = 6*5 = 30

The three sides are 15 cm, 25 cm, 30 cm.

As a check:

15+25+30 = 40+30 = 70

and note how the ratio 15:25:30 reduces to 3:5:6 after dividing all three parts by the GCF 5

Both conditions are satisfied, so we have confirmed our answers.

Answer:

Step-by-step explanation:

(3x) + (5x) (6x) = 70

= 14 = 70

70/14

= 5

Suppose that f(x) is an EVEN function and let the integral f(x) dx from 0 to 1=5 and the integral f(x) dx from 0 to 7 =1. What i

Cerrena [4.2K]

Since it's even, the integral from -7 to -1 is the same as the integral from 1 to 7.
think about
x^2 from 0..1,its 1/3
from 0..7 its 7^3/3
from -1..7 its 7^3/3+1/3

from -7..-1 of x^2 its -1/3+7^3/3 to get this without integrating we just do 7^3/3-1/3 which is the integral from 0..7 minus the integral from 0..1
So the integral from 1 to 0 f(x) dx = 5 changes to the integral from 0 to 1 f(x) dx = -5 and you add it to the integral from 0 to 7 which is 1 making -4

What is 1556 rounded to the nearest thousand

fgiga [73]

Greetings!

"What is 1556 rounded to the nearest thousand?"...

The thousand place value number is in bold: 1556.

Since the number to the right of the bold number is 5 or greater, we round up.

1556 rounded from the thousand place value is 2000.

Hope this helps.

4ab (a -b) + b (2b -2a²) for a = 1 and b= -1 simplify it

aleksley [76]

Answer:

Step-by-step explanation:

4ab(a-b)+b(2b-2a^2)

=4*1*-1[1-(-1)]+(-1){2(-1)-2*1^2}

=-4(1+1)-1{-2-2}

=-4*2-1(-4)

=-8+4

=-4
