Answer:
9y-3y=6y is equivalent to 9y – 3y.
the answer is D the last one,
the reason is just that any negative number is automatically smaller than a positive number. so -2.8 is smaller than even the smallest decimal possible as long as that decimal is positive. 1.4 is actually about 3 time more that -2.8
(both are still freezing cold)
Answer is 5.4 units
Step by step.
I used Pythagorean theorem to find the diagonal (hypotenuse) of the triangle.
We know the height (y) is 5 and the other leg (x) is 2.
a^2 + b^2 = c^2 is the formula.
Substitute the two legs in for a and b.
5^2 + 2^2 = c^2
29 = c^2
Now take the square root of both sides
5.385 = c
Round to nearest tenth = 5.4 units
