Distributive is
a(b+c)=ab+ac
ab+ac=a(b+c)
perimiter of a rectangle=distance around
we have
P=L+W+L+W if we go around
so
P=L+L+W+W
P=2L+2W
undistribute 2
P=2(L+W)
10^9 (Ten to the power of nine)
Answer:
24 cm
Step-by-step explanation:
since the two triangles are similar,
10cm/20cm = 36cm _ h/h
Answer:
parallel line slop2 = -5/4
perpendicular line slope = 4/5
Step-by-step explanation:
If 2 lines are parallel, they will have equal slopes.
Therefore, the slope of a line parallel to y = 1/4 - 5/4 x will be -5/4
If 2 lines are perpendicular, their slopes are negative reciprocals of each other. So the slope of the perpendicular line = -1 ÷ -5/4 = 4/5
