If UV = x + 13, VW = 15, and UW = 7x + 16, what is UW?
marusya05 [52]

Answer:

UW = UV + VW

substitute:

7x + 16 = (x + 13) + (15) \\ 7x + 16 = x + 28 \\ 7x - x = 28 - 16 \\ 6x = 12 \\{ \underline{  \:  \: x = 2 \:  \: }}

then find UW:

UW = 7x + 16 \\  = 7(2) + 16 \\  = 14 + 16 \\  \\ { \boxed{ \boxed{ \:  \: UW = 30 \:  \: }}}

What’s the answer???(ONLY ANSWER IF YOU KNOW PLEASE)
aleksandr82 [10.1K]

Answer:

D

Step-by-step explanation:

Nothing gets rid of the square root signs. That makes a and b incorrect as answers without doing a single calculation. Now the race is on between c and d.

The dot between f and g only means that f(x) and g(x) are multiplied together. There is nothing in that statement that helps us distinguish c and d.

So the two roots are multiplied together f·g(x) = √[(x + 7)(x - 2)]

Expand the two terms between the square brackets and you get

[x^2 + 7x - 2x - 14]. When you combine like terms you get

[x^2 + 5x - 14] or f·g(x) = √(x^2 + 5x - 14]

The answer is D

Polygon WXYZ has vertices W (-1.5, 1.5)X(6, 1.5) Y(6, -4.5) and Z (-1.5, -4.5 )is WXYZ a rectangle
QveST [7]

Answer:

WXYZ is a rectangle

Step-by-step explanation:

∵ W = (-1.5 , 1.5) , X = (6 , 1.5)

∴ WX is a horizontal segment ⇒ same y-coordinates

∴ WX = 6 - -1.5 = 6 + 1.5 = 7.5 units ⇒ (1)

∵ Y = (6 , -4.5) , X = (6 , 1.5)

∴ XY is a vertical segment ⇒ same x-coordinates

∴ XY = 1.5 - -4.5 = 1.5 + 4.5 = 6 units ⇒ (2)

From (1) and (2) WX ⊥ XY

∵ Y = (6 , -4.5) , Z = (-1.5 , -4.5)

∴ YZ is a horizontal segment ⇒ same y-coordinates

∴ YZ = 6 - -1.5 = 6 + 1.5 = 7.5 units ⇒ (3)

From (1) and (3)

∴ WX // YZ and WX = YZ

∴ WXYZ is a rectangle ⇒ 2 opposite sides are parallel and equal

  and 2 adjacent sides are ⊥
