Need Help Solving To Complete The Square

Answers

Answer 1

Answer:

b=9 and b=-21

Step-by-step explanation:

first step: move 195 to the other side by adding to get:

b^2+12b=189

now to find the constant you take the b value which is 12 divide that by 2 and square it. then add the product to both sides. 12/2=6, 6^2=36

b^2+12b+36=189+36

next factor b^2+12b+36.

(b+6)^2=225

square root both sides to get:

b+6=15 and b+6=-15

solve by subracting 6 to both sides and you get the 2 final answers.

b=9 and b=-21

Answers

Answer:

1.4 ft

Step-by-step explanation:

Ok so first off you want to take the area(1.96) and divide it by your height(1.4)

This will get you B!(1.4)

Also since this is a square all the sides are equal!

Answer: b= 1.4

Step-by-step explanation:

Area = length x width

1.96 = “b” x 1.4

Since we have the area and one side of the box, we can rearrange the equation to find the missing side.

Since 1.4 is being multiplied on the right side of the equation, we must divide by 1.4 to remove it. Divide both sides by 1.4

1.96/1.4= b

b= 1.4

if you think about the equations as linear functions, you can imagine that if they do intersect, it must be on only one point (since two straight lines cant intercept at more than one point, unless they are the same line)

therefore the point has to be the one and only intercept- satisfiing both linear equations

The residence of a city voted on whether to raise property taxes the ratio of yes votes to no votes was 7 to 4 if there were 3672 no votes what was the total number of votes

Answers

Answer: 10,098 votes

Step-by-step explanation:

The ratio is 7 : 4 which means that for every 7 yes votes, there were 4 no votes.

To find the total votes, add the ratios:

= 7 + 4

= 11

4/11 are the no votes out of the total. Assuming the total is x, the formula is:

4/11x = 3,672

x = 3,672 / 4/11

x = 10,098 votes

He opened the small door on the box and used his thumb to pull down the lever. Dorsey then headed back to the scene of the fire, not realizing that he'd made a mistake he had forgotten to pull down the lever four times, a special signal that would have made it a true second alarm. At the Courthouse, Schaffer and Brown would hear Dorsey's alarm, but, assuming it was simply another signal telling them about the original fire, they failed to call out more engines.How does this excerpt support the main idea of the passage?It illustrates how many mistakes firefighter Dorsey made during the course of the fire.It demonstrates how the citys fire alarm system and signal boxes worked.It describes one of the key mistakes that prevented the fire from being extinguished sooner.It highlights the fact that Bruno Goll was responsible for the fire and stopped it from being put out. pls pls pls pls helpppp it's 12:10am 5.
