Part A: If (62)x = 1, what is the value of x? Explain your answer.
Zielflug [23.3K]
The first one is the second one is All real numbers Step- by-step explanation:
1. Anything raised to the " zeroth" power is always 1
2. Because 7 is being raised to the zeroth power, the number inside the parentheses becomes 1. Now x can equal anything, 1 times itself will always equal 1, no matter how many times you multiply them.

Rectangle ABCDABCDA, B, C, D is graphed in the coordinate plane. The following are the vertices of the rectangle: A(-7, -5), B(-
sergey [27]

The length of side CD is equal to 11 units.

Given coordinates of rectangle are A(-7,-5), B(-7,6),C(-4,6) ,D(-4,-5)

We are require to find the length of side CD.

Rectangle is a two dimensional figure whose two opposite sides are equal to each other. Distance between two coordinates is the equal to length of a side.

We know that the distance means how far two points are located.

Coordinates of  A(-7,-5), B(-7,6),C(-4,6) ,D(-4,-5).

Distance=\sqrt{(x_{2} -x_{1} )^{2} +(y_{2} -y_{1} )^{2} } where (x_{1} ,y_{2} )(x_{2} ,y_{2} ) are the coordinates of two ends of a line.

CD=\sqrt{(-5-6)^{2} +(-4+4)^{2} }

=\sqrt{11^{2}+0^{2}  }

=\sqrt{121}

=11 units.

Hence the length of side CD is 11 units.

A right triangle is ____ a scalene triangle.<br> Always, sometimes, or never
konstantin123 [22]

Answer: Sometimes

Step-by-step explanation:

This is a very tricky question. We know that in an isosceles triangle, two sides are the same. Because of this, we know that the right angle is always 90 degrees, and the other sides would be 45 degrees each because all triangles add up to 180 degrees. A right triangle could also be scalene, meaning none of the sides are the same, for example a scalene triangle could have sides of 44, 46, and 90 degrees. Rest assured, a right triangle will never be equalateral. Hope this helps :) Merry Christmas
