Answer:
Step-by-step explanation:
Semicircle:
diameter = length of the rectangle = 25 cm
Half circumference = πd/2
= 3.14 * 25/2 = 39.25 cm
Perimeter of the figure = 39.25 + 20 + 25 + 20
= 104.25 cm

Step-by-step explanation:
Find two number that multiplies - 63 and add - 2
9 & 7 are both the greatest common factor
Neither of the options are correct for the given equations.
Step-by-step explanation:
-x+y=4...................................................1
16x+y=-3...............................................2
Subtract equation 1 and 2
-x+y- 16x -y = 4+3
⇒ -17x = 7
⇒x=
⇒x= -0.4117
so,
16×-0.4417 + y = -3
⇒y= -3+6.5872
⇒y= 3.5872
So the point of intersection is (-0.4117, 3.5872)
