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)

first correct answer will make brainliest

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

22.83 repeating

step-by-step explanation:

137 ÷ 6 is 22.8333333 therefore we understand that 3 is repeating.

happy to

pls mark as brainliest

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
