A = (1/2)*b*h
Base is the vertical length from y1 to y2 = 6
Perpendicular height is the length from x3 to the base = 7
A = (1/2)*6*7
A= 21 units^2
Answer:
3x² - 12x - 36
= 3(x - 6)(x + 2)
Step-by-step explanation:
3x² - 12x - 36 Find any common factor. All terms are divisible by 3.
= 3(x² - 4x - 12) Find two numbers that sum to -4 and whose product is -12. Replace -4 with these two numbers.
= 3(x² - 6x + 2x - 12) Group the terms splitting from the middle
= 3( (x² - 6x) + (2x - 12) ) Find the common factor in each group.
= 3( x(x - 6) + 2(x - 6) ) The groups have a common factor (x - 6).
= 3( (x - 6)(x + 2) ) Remove the extra brackets
= 3(x - 6)(x + 2) Fully factored
