Answer:
x = 26
Step-by-step explanation:
because JKL is 90 degrees
x+8 + 2x+4 =90
3x + 12 =90
3x = 78
x = 26
Answer:
area = 2x² - 17x - 21
Step-by-step explanation:
Area of the rectangle is:
area = (width*length)
area = (x+7)*(2x-3)
= x*2x + x*-3 + 7*2x + 7*-3
= 2x² - 3x - 14x - 21
= 2x² - 17x - 21
Do you mean x/-9=(-4)-(-11)x?
(-5,-10)E
(-5,-3)F
(-3,-10)G
