the required equation will be:
-5( 7w+ 8)= 30
-35w- 40= 30
-35w= 30+ 40( as 40 is taken to the other side, its symbol changes)
-35w= 70
W= 70/-35
W= -2
Answer:
54 movies
Step-by-step explanation:
shelving unit has 4x + 6 movies
and each holds 12 movies,
then x =12
Then solve 4x + 6 for x= 12
4(12) + 6 = 54
Answer:
60-32i
Step-by-step explanation:
(8-2i)^2=8^2-2.8.2i+(2i)^2
=64-32i+4i^2
=64-32i-4
=60-32i
The length of the rectangle is 10 cm and perimeter of the rectangle is 32 cm.
Step-by-step explanation:
Given,
The area of rectangle = 60 sq cm
Width (b) of the rectangle = 6 cm
To find the length and perimeter of the rectangle.
Formula
The area of the rectangle = l×b
The perimeter of the rectangle = 2(l+b)
According to the problem,
l×b = 60
or, l×6 = 60
or, l = 60÷6 = 10
Length (l) = 10 cm
Perimeter = 2×(10+6) cm = 32 cm
