Will equal 8 times that same number. This is because you have 6x and are subtracting -2x. Subtracting a negative is like adding a positive.
Answer:
644
Step-by-step explanation:
SA=[2×(5×20 + 5×6 + 20×6)] +
[2×(4×12 + 4×6 + 12×6)] -
[ 2× 12×6]
= [2×(250)]+[2×(144)] - [144]
= 500+288-144
= 644 cm²
Answer:
f(x) = -5x - 14
Step-by-step explanation:
this table represent a straight line : y = mx +c
first find m which is the slope
m = (-24 - -19)/(2-1) = -5
then find c
-19 = -5(1) + c , c = -14
thus f(x) = -5x -14
Answer: Width is 3 cm
Explanation: since the formula for area of a rectangle is length*width= area, plug the numbers in. 12*x=36. So, what times twelve equals 36? 3! You can also view it like this, 36/12, which would also get you three.
