Which equation would be solve the following problem? the height of a triangle is 5m less than its base. the area of the triangle is 42m^2.
find the length of the base?

42=x(x-5)

42=1/2(x)(x-5)

42=x^2-5

42=1/2(x^2-5)

Part 1)

Part 2) The length of the base is

Step-by-step explanation:

Part 1) Which equation would be help solve the following problem?

Let

x----> the length of the base of a triangle

y----> the height of a triangle

we know that

The area of a triangle is

so

------> equation A

-----> equation B

Substitute equation B in equation A  

Part 2) Find the length of the base

we have

solve for x

Solve the quadratic equation by graphing

The solution is

see the attached figure

answer: 91

step-by-step explanation:

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
