Polygon pqrst shown below is dilated with a scale factor of 3 l, keeping the origin as the center of dilation:
which statement about polygon pqrst and its image after dilation, polygon p’q’r’s’t, is correct?
the length of diagonal ps and diagonal p’s’ are in the ratio 1: 3
the lengths of side pt and side r’q’ are in ratio 1: 3
the length of side pt is equal to the length of side p’t’
the measures of angle s and angle s’ are in the ratio 1: 3

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

isn't it a pentagon? sense [3 (triangle) + 4 (rectangle)] - 2 (triangle and rectangle connected) = 5 (pentagon)
