Answer:
(x2+3) • (x2+9)
Step-by-step explanation:
Factoring 
The first term is, 
its coefficient is 1 .
The middle term is, 
its coefficient is 12 .
The last term, "the constant", is +27
Step-1 : Multiply the coefficient of the first term by the constant 1 • 27 = 27
Step-2 : Find two factors of 27 whose sum equals the coefficient of the middle term, which is 12 .
27 + 1 = 28
9 + 3 = 12 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -9 and -3
x4 + 9x2 + 3x2 + 27
Step-4 : Add up the first 2 terms, pulling out like factors :
x2 • (x2+9)
Add up the last 2 terms, pulling out common factors :
3 • (x2+9)
Step-5 : Add up the four terms of step 4 :
(x2+3) • (x2+9)
$2.76/18 • $2.07/x cross multiply these proportions $2.76•x = $2.76x. $2.07•18= $37.26 then divide by 2.76 on both sides $2.76/$2.76 that cancels out and you get x $37.26/$2.76= 13.5 so that means x= 13.5 your answer is 13.5

brainly.com/question/2359153t + s = 925....s = 925 - t
4t + 6s = 4524
4t + 6(925 - t) = 4524
4t + 5550 - 6t = 4524
-2t = 4524 - 5550
-2t = -1026
t = 1026/2
t = 513 <== 513 turkey sandwiches
t + s = 925
513 + s = 925
s = 925 - 513
<span>s = 412 <=== 412 steak sandwiches</span>
calculate rise over run = 37 ÷ 63
Answer:
a = 6
Step-by-step explanation:
use distribution method:
-3(4-a) = 6
-12+3a = 6
3a = 6+12
3a = 18
a = 18/3 = 6
