The box of 100 would be the better deal, considering buying 2 boxes of 50 would turn out to be $47.00
If triangles PQR and STU are similar then PQ corresponds to ST and PR corresponds to SU. Therefore, PQ/ST=PR/SU
Considering that, PQ= 7-x, ST= 13-x, PR= x²+5 and SU= x² +20
therefore, (7-x)/(13-x)= (x²+5)/(x²+20)
cross multiplying,
7x² +140-x³+20x =13x²+65-x³-5x
combining the like terms,
6x² +15x -75=0
solving for x,
x = 5/2 or -5
Answer:
22 centimeters
Step-by-step explanation:
<em>1. See how many centimeters are in a meter:</em>
There is 100 centimeters in one meter
<em>2. Multiply each number by 100 to convert the meters to centimeters </em>
0.98 x 100= 98
0.76 x 100 = 76
<em>3. Subtract to find the difference </em>
98 - 76 = 22
<u>Hence, the blue string is 22 centimeters longer than the yellow string.</u>
<u><em>have great night! :D</em></u>
A. 12•8=96, 96/2=48, 48•4=192, 12•12=144, 192+144=336
