Hello,
A :4x²-4x-120=2(2x²-2x-60) is TRUE
B: 4x²-4x-120=4(x²-x-30) is TRUE
C: 4(x+6)(x-5)=4(x²+x-30) is FALSE
D: 4x(x-1)-120=4x²-4x-120 is TRUE
Look for the graph that intersects the y-axis at -3.
From that point, count 3 spaces up and 4 spaces to the right, then place your second point.
Continue to do this until you see your line match up to one of your choices.
Answer:
√(74)
Step-by-step explanation:
Pythagoras's Method: a^2+b^2 = c^2 (only works on right triangles)
Put the numbers in:
5^2+7^2 = C^2
c^2 = 74
c = √(74)
Hope it helps! <3
