Answer:
40 times.
Step-by-step explanation:
4+4+12=(20 x 2)=40
Answer:
Following the rule of BIDMAS
we will solve the one inside the bracket first, Addition will be solved before subtraction
i.e ( 5+4-2) x ( - 2)
= ( 9-2) x (-2)
= 7 x -2
= - 14
Step-by-step explanation:
Perpendiculare has slope taht mulitpliest so -1
y=mx+b
m=slope
y=4x-3
slope is 4
4 times what=-1
what=-1/4
the equation of a line that passe through (x1,y1) and has a slope of m is
y-y1=m(x-x1)
given
(8,11) and m=-1/4
y-8=-1/4(x-11)
y-8=-1/4x+11/4
y=-1/4x+43/4
x+4y=43
Perimeter = 2L + 2W
42 = 2(12) + 2W
42 = 24 + 2W
-24 -24
18 = 2W
/2 /2
9 = W
The answer is 9 feet wide
