Answer:
x = 8
Step-by-step explanation:
Let us take the breadth as 'x'
breadth = x
length = 3 + x
perimeter = 38m
perimeter of a rectangle = 2 ( l + b )
= 2( x + x + 3 ) = 38
4x + 6 = 38
4x = 38-6
x = 32/4
x = 8
breadth = 8
length = 11
Answer:
D
Step-by-step explanation:
i think D because this line -- means division therefore 9 divided by 10
Reflecting through x=0 maps x to -x so
g(x) =f(-x) = -2x
Answer: y = -2x
Can't see the choices, look for a downward slope of two units down for every unit to the right, through the origin.
