Answer:
1.6 meters
Step-by-step explanation:
20.65-15.8=4.85
4.85/3=1.6
Answer: 160m
Explanation: I hope this helps <3
<span>So we need to find the solutions to the equation (x+6)y=9 so we can arrange them in pair (x,y). We simply plug in the numbers into the equation. First pair (-5,9), we get (-5+6)9=9 so 1=1 and that is true, so first pair works. Second pair: (-3+6)3=9 we get (3)3=9 and 9=9 so second pair also works. Third pair: (3+6)1=9 we get 9=9, also works. Fourth pair: (7+6)9=9 we get 13*9=9 and 117=9 which is false so the fourth pair can't be a solution for the equation. The correct answers are A, B and C.</span>
hi
f(x) = (x+9) (x-4)
if it's cross the x axis it's means f(x) = 0
(x+9) (x-4) = 0 means x+9 = 0 so x = -9 and x-4 = 0 so x = 4
answers f(x) = 0 for x = -9 and x = 4
Answer: z=45 x=45 y=90
Step-by-step explanation:
Z is linear pair to 135 so 180-135 =45
the opposite sides of X and Z are congruent therefore by ITT or CITT one of them i don’t remember which the opposite angles are congruent. lastly all angles in a triangle are 180 so 45+45 =90 180-90=90
