What is the value of b2 - 4ac for the following equation? 2x 2 - 2x - 1 = 0

Orlov [11]

For you to make an equation a quadratic equation, you need everything to be on one side, so you add one to both sides.

2x^2 + 3x + 0=0 

a=2, b=3, c=0 

b^2-4ac (In the next step just plug in your variables) 

3^2 - 4(2)(0) 

9 - 8(0) 

9 - 0 

Your answer=9

Nathaniel builds birds and birdhouses using Lego blocks. Let BBB represent the number of birds and HHH represent the number of b

vladimir1956 [14]

Answer:

Step-by-step explanation:

Given that:

$43B+215H \leq 3000$

where:

B represents the number of birds
H represents the number of Birdhouses

Nathaniel wants to build 50 birds(B) using lego Blocks, we want to determine how many birdhouses(H) he can build with the remaining Lego blocks.

If B=50

$43(50)+215H \leq 3000\\2150+215H \leq 3000\\\text{Subtract 2150 from both sides}\\215H \leq 3000-2150\\215H \leq 850\\\text{Divide both sides by 215}\\H \leq 3.95$
