Answer:
Step-by-step explanation:
40 : 30 = x : 63 ⇒ x = (40*63)/30 = 84
y = 59°
<span>If a quadrilateral has four congruent sides and four right angles, then it’s a square (reverse of the square definition).

The midpoint of PQ : ( - 6 , - 3 ).
P ( - 1, - 4 ); Q ( x , y )
- 6 = ( - 1 + x ) / 2
- 1 + x = - 12
x = - 12 + 1 = - 11
- 3 = ( - 4 + y ) / 2
- 4 + y = - 6
y = - 6 + 4 = - 2
Answer: A ) Q ( - 11, - 2 )
Answer:
- 5
Step-by-step explanation:
The equation of a line in slope - intercept form is
y = mx + c ( m is the slope (gradient) and c the t- intercept )
y = 3x - 8 ← is in slope- intercept form
with gradient m = 3 and y- intercept c = - 8 , thus
m + c = 3 + (- 8) = 3 - 8 = - 5
6) x=-2
7) b = 195
8) v = -17
9) x = 20
10) x = -260
