1. add 40 to the 40 and 25
2. now you have
\frac{5x {}^{2} }{5}   = \frac{65}{5}
3. then you have
{x}^{2}  = 13
4. then square root
{x}^{2}  = 13
5.then round answer to nearest tenth which is
x = 3.61

Given that ABCD is a rhombus, find the value of x.<br> (X+14)
Kay [80]

Answer:

option B. x=38^o

Step-by-step explanation:

we know that

1) The two diagonals of a rhombus are perpendicular

2) The sum of the interior angles in any triangle must be equal to 180 degrees

Let

O ----> the intersection point of the diagonals of the rhombus

In the right triangle OAD

x^o+(x+14)^o+90^o=180^o

solve for x

x^o+(x+14)^o=90^o

2x=90^o-14^o

2x=76^o

x=38^o

Help me with these 3 questions, please
Zina [86]

Answer:

1. x = -4y ---> y = (-1/4)x

slope = -1/4. y-intercept = (0,0)

2. y = -2x + 4

3. y = (1/3)x - 1

Step-by-step explanation:

1. Re-write your equation so that x is on the right and y is on the left:

x = -4y ---> y = (-1/4)x

slope = -1/4. y-intercept = (0,0)

2. y-intercept = (0,4) ----> P1

x-intercrpt = (2,0) ----> P2

slope m = (y2 - y1) / (x2 - x1)

= (0 - 4)/(2 - 0)

= -2

therefore, y - y1 = mx - x1 ---> y - 4 = -2x

or y = -2x + 4

3. y-intercept = (0,-1)

x-intercept = (3,0)

m = (0 - (-1)) / (3 -0) = 1/3

y - (-1) = (1/3)x - 0 ---> y = (1/3)x - 1
