The perimeter of the square is equal to the perimeter of the triangle. What are the side lengths of each figure? square: ? units
blsea [12.9K]

Answer:

<em>Square= 12 units</em>

<em>Triangle long sides= 19 units</em>

<em>Triamgle short side= 10 units</em>

Step-by-step explanation:

<em>It is a square, so all sides are the same.  That means 3x+3 equals 4x.  What number can be subsituted into x to equal 4?  If x is 3, then 3x+3 would be 3(3)+3.  It equals 12.  4 times 3 is also 12.  It works!  That also means the square's side is 12 units.</em>

<em>Square= 12 units</em>

<em />

<u><em>So, x=3</em></u>

<em />

<em>The triangle's longer sides are 7x-2.  Subsitute x in, which is 3, and you get 7(3)-2.  It equals 19.  The two longer sides of the triangle are the same length, so both are 19 units.</em>

<em>Triangle long sides= 19 units</em>

<em />

<em>The triangles shorter side is 2x+4.  Subsitute 3 in for x and you get 2(3)+4.  It equals 10, so the shorter side is 10 units.</em>

<em>Triangle short side= 10 units</em>

During a four-week period, you worked the following hours: Week 1- 363 /8 hr; Week 2- 411 /4 hr; Week 3- 401 /2 hr; Week 4- 383
Dafna11 [192]
The average number of hours can be calculated using the following rule:
average number of hours = total number of hours / total number of weeks

total number of hours = 36 3/8 + 41 1/4 + 40 1/2 + 38 3/8 = 313/2 hours
total number of weeks = 4 weeks

Average number of hours per week = (313/2) / (4) = 39 1/8 hour

Based on the above calculations, the correct answer is:
C. 39 1/8 hour

A pail hold 6 3/4 gallon of water. how much is this in cups
Ber [7]
There are 16 cups in 1 gallon so you would have to turn the denominator in the fraction into a 16 meaning you would multiply by 4 (because 4 goes into 16, 4 times). Your new fraction is 12/16. now you do 6 gallons*16 cups and you get 96 cups. Then you add the fraction onto 96 and you would be adding 12. Your final answer is 108 cups in 6 3/4 gallons

(18) POINTS pLEASE HELP
JulijaS [17]

Answer:

(x-4)(x-3)

Step-by-step explanation:

x^{2} -7x+12\\

multiply 1 and 12= 12

find two numbers that multiply to get twelve AND add together to get -7(the middle number)

the two numbers are -3 and -4 (they add up to get -7 AND multiply together to get 12)

plug in these numbers for -7x

x^{2} -3x-4x+12

x(x-3)-4(x-3)

the bolded is the first binomial and the second binomial is in the parenthesis.

(x-4)(x-3)

I hope this helps!
