Answer: Fourth option:

v = √( z*(z + w ) )

Step-by-step explanation:

Ok, v is the hypotenuse of the larger triangle, we know, by the Pythagorean's theorem, that:

v = √(y^2 + z^2)

now, in the smaller triangle we have that:

x = √(y^2 + w^2)

And we also know that:

z + w = √(x^2 + v^2)

(z + w)^2 = x^2 + v^2

and x^2 = (y^2 + w^2)

(z + w)^2 = z^2 + w^2 + 2*z*w = y^2 + w^2 + v^2

v = √( z^2 + w^2 + 2*z*w - y^2 - w^2)

v = √( z^2 + 2*z*w - y^2 )

and y is the altitude of the larger triangle rectangle, so, by the geometric mean theorem, we have that:

y^2 = z*w

v = √( z^2 + 2*z*w - z*w ) = √( z^2 + z*w  ) = √( z*(z + w ) )

The correct option is the fourth one.

E-4 - 5 - 6 - → The perimeter of a rectangle is 425 yards. The length and width of the rectangle are each multiplied by 6. What
Alex73 [517]

Answer:

2550yards

Step-by-step explanation:

Perimeter of a rectangle = 2L + 2W

L is the length

W is the width

If perimeter of a rectangle is 425 yards, then;

425 = 2L + 2W

425 = 2(L+W)

L+W = 425/2 .... 1

If the length and width of the rectangle are each multiplied by 6

P = 6(2L) + 2(2W)

P = 12L + 12W

P = 12(L+W) .... 2

Substitute 1 into 2

P = 12(425/2)

P = 6*425

P = 2550yd

Hence the perimeter of new triangle is 2550yards
