Answer:
"all real numbers."
Step-by-step explanation:
Subtract 13 from both sides, obtaining -5x = -5x.
This result is true for all x, so the solution set is "all real numbers."
In a 45 · 45 · 90 triangle, the hypotenuse is √2 · legs, because a 45 · 45 · 90 triangle is isosceles, so the legs are the same length. So, we have 3√2 · √2 = 6, so the hypotenuse is 6.
x=6
Answer:
90 inches squared
Step-by-step explanation:
Formula for a rhombus is simply the diagonals over 2.
(The diagonals here are 12 and 15)
You could also do this intuitively. Because there is an inscribed right angle, each of the triangles inside are BH/2. Thus, the area of all four is 2BH. The base and height of each of the triangles is 6 and 7.5, so the area is 6 * 7.5 * 2.
Answer:
32
Step-by-step explanation:
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
3 feet west + 4 feet east means that the length of the rectangle is 7
2 feet south and 1 foot north means that the height (or width) 3.
Since the rectangle is 3 ft by 7ft the total distance around (perimeter) is 2 (l+w) or in this case 2 (7 +3) = 2 (10) = 20 ft Answer b
Drawing a picture helps.
