Answer:

x = 1, -2/7

Step-by-step explanation:

You could use the quadratic equation but this can be factored into

(7x + 2) (x - 1). You can verify that by multiplying it out.

Since (7x + 2) (x - 1) = 0, if either factor is 0 then the equation would be equal to 0, thus we get x = 1, -2/7

mash [69]

Answer:

-12

Step-by-step explanation:

-|-12| = (-1)*| -12 | = - 12.

Recall the meaning of the absolute value function: It always returns a zero or positive result. Here, | -12 | = +12. Now, if there's a negative sign in front

of | -12 |, the final answer is -12.

Mike measured the stage where his band was going to play to determine if it is a right triangle. Does the stage with side length

katrin [286]

Answer:

let

hypotenuse[h]=60ft

base[b]=36ft

perpendicular [p]=48ft

by using Pythagoras law

p²+b²=h²

48²+36²=60²

2896≠3600

since p²+b²≠ h²[so the stage is not in a right angled triangle]but it is scalene triangle

Determine whether one figure is a dilation of the other.

Alika [10]

The answer is no.

A dilation is when a shape is scaled up or down to create a similar shape. The only thing that changes is the lengths of the sides. The angles will stay the same.

In this case, the original has angles 54, 29, and 97.

After the transformation the triangle has the angles 29, 59, and 92.
