Answer:
5.9
Step-by-step explanation:
Area of a triangle is 1/2 base times height. the base is the horizontal part of the triangle and the height is the vertical part. Since it a isosceles they are equal. Those two segment are also called the legs (remember that for later). 4x4=16 times 1/2 equal 8 cm squared. So know me must find the hypotenuse. Since we since dealing with a right triangle we are going to use pythagorean theorem which is

where a and b are the LEGS and c is the hypotenuse. the legs are also known as base and height so we use

which simplify to



which is about 5.9
Algebraic expresion: 56-2x
First, take half of the coefficient of 18x then square it.
18 / 2 = 9
9^2 = 81
So, D. 81 is the answer.
Answer:
6 miles
Step-by-step explanation:
Since you walked 3/4 miles in 1 day then in 8 days you walked...
3/4*8=3*2=6 miles
