Step-by-step explanation:
first ..
subtract 2 on both sides 2-2...2-y
then you should have 1/2x =y-(-2) then divide
B is the correct answer, i believe
Answer:
x = 4
Step-by-step explanation:
Since the rectangles are similar, use a ratio.
15/6 = 10/x
or
6/15 = x/10
I will use 15/6 = 10/x to solve this problem, but both ratios should work to solve this problem.
15/6 = 10/x
Cross Multiply:
6(10) = 15x
Solve:
60 = 15x
x = 4
The lateral area is 192 cm².
The lateral area is the area of all of the lateral faces. Since the base of the pyramid is a quadrilateral, there are 4 lateral faces. The area of one lateral face is 48 cm²; this means the lateral area is 48(4) = 192 cm².
