Answer:
b=-3
Step-by-step explanation:
4b+3=-9
-3 -3
subtract 3 from both sides like so. 3-3 cancels out. -9-3=-12.
4b=-12
youre left with 4b=12 so DIVIDE 4b by 4 and -12 by 4
4b/4=-12/4
4b divided by 4 is 1. -12 divided by 4 is -3
b=-3
plug -3 in for b to make sure its correct
4(-3)+3=-9
-12+3=-9
-9=-9
First, find the hypotenuse of the triangle with leg lengths 4 and 4. Use special triangle theorem:
1:1:sqrt(2) 4:4:4*sqrt(2)
Use the Pythagorean Theorem to find x:
2^2 + (4sqrt2)^2 = x^2
x^2 = 36
x = 6, or choice (D).
