Answer:
B. -4.
Step-by-step explanation:
8-(4c-5)=11
8-4c+5=11
13-4c=11
-4c=-2
C=1/2
Answer/Step-by-step explanation:
a. Diagonals of a rectangle are equal to each other. Therefore:
9x + 20 = 10x + 8
Collect like terms
9x - 10x = -20 + 8
-x = -12
Divide both sides by -1
x = 12
b. One of the properties of a rhombus is that, a diagonal of a rhombus bisects the angles of a rhombus. Therefore, this means that:
2x + 15 = 5x + 3
Collect like terms
2x - 5x = -15 + 3
-3x = -12
Divide both sides by -3
x = 4
Answer:
x² + y² = 144
Step-by-step explanation:
The general equation of a circle is given as
(x - a)² + (y-b)² = r²
where a and b are the center of the circle along the x and y axis respectively and r is the radius of the circle.
Hence a circle that has its center at the origin and has a diameter of 24 units, we can deduce that the values of a,b are 0,0. Also,
radius = diameter/2
= 24/2
= 12 units
Hence the standard equation of the circle
(x - 0)² + (y - 0)² = 12²
x² + y² = 144
