Aright triangle has a hypotenuse of 70 feet and a leg of 35 feet. what is the length of the other leg?

a. 51 feet

b. 61 feet

c. 78 feet

d. 80 feet

The Pythagorean Theorum formula is a^2+b^2=c^2.

The hypotenuse equals c. Let's say that the 35-foot leg is b. That makes our formula c^2-b^2=a^2.

C Squared=4,900

B Squared=1,225

C Squared-B Squared=3,675

If we square root 3,675, that gives us our final answer, 60.6. Let's round it to 61.

The answer would now be B.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
