I believe it is 2 feet because area is base multiplied by height. So, 3 x 2/3 is 2.
Answer:
13x^2+2x+5
Step-by-step explanation:
that is the right answer
You have to combine the like terms.
Take a photo of it and then put the photo in Photo math
The ladder, the wall and the floor form together a triangle rectangle, where the ladder is the hypotenuse of the triangle and the floor and wall are the cathetus. We know from Pythagoreas theorem that the square of the hypotenuse is equal to the sum of the two cathetus squared added, so we can write an equation with the data we have:
hyp^2 = cath1^2 + cath2^2
<span>hyp^2 = wall^2 + floor^2
</span>so we have the hypotenuse value, the floor value and the unknown is the wall height:
(22)^2 = wall^2 + (7)^2
484 = wall^2 + 49
wall^2 = 484 - 49 = 435
wall = √435
wall = 20.9
therefore the ladder touches the wall 20.9 feet above the ground
Answer: 464 km²
Step-by-step explanation:
We will break this shape up into two parts. You can do this in two different ways, see attached for how I did it.
Area of a rectangle is A = L * W;
40 km * 9 km = 360 km²
13km * 8 km = 104 km²
Now we will add them together for total area:
360 km² + 104 km² = 464 km²
