Need help with left side

Hello,

1) k = (-5) * (-5) = 25

3) x = 12 * 0 = 0

5) y = (-4) * (-12) = 48

7) z = 0 * 9 / 1 = 0

9) x= 18 / -3 = -6

11) p = -8 / 8 = -1

13) h = 42 / 14 = 3

15) m = -42 / 6 = -7

17) x = -9 * -11 = 99

19) v = -17 / -17 = 1

21) h = 3,136 / 56 = 0,056

23) x = 4,200 / 30 = 0,14

25) m = 21 * -3 = -63

Bye :)

What's the length of side AB in ∆ABC shown? A. 5 B. √313 C. 6 D. √15

HACTEHA [7]

Answer:

The value of x = 5 units.

Step-by-step explanation:

Given the right-angled triangle ∆ABC with the following dimensions

AC = a = 12

BC = c = hypotenuse = 13

AB = b = x

Pythagorean Theorem

For a right-angled triangle with the sides, a and b the hypotenuse c is defined as:

$c=\sqrt{a^2+b^2}$

Thus, using the Pythagorean Theorem to determine the value 'x',

$b=\sqrt{c^2-a^2}$

as b = x, so

$x=\sqrt{c^2-a^2}$

a = 12

c = 13

$x=\sqrt{13^2-12^2}$

$x=5$

Therefore, the value of x = 5 units.

What equation represents the line that passes through the points (-3 7 and (3 3?

dexar [7]

Hello : let A(-3,7) B(3,3)
the slope is : (YB - YA)/(XB -XA)
(3-7)/(3+3) = -2/3
an equation is : y=ax+b a is a slope

y = (-2/3)x +b

the line through point B (3,3) : 3 = (-2/3)(3)+b
b =5
the equation is : y =(-2/3)x+5
