The factors are -70 and 41
-70 x 41 = -490
-70 + 41 = -21
Hope this helps!
        
             
        
        
        
Answer:
9) x=58
10) r=4
11) m=4
12) p=3
13) x=6
14) x=-3
15) s=400
Step-by-step explanation:
9) x+2/5=12
     x5  x5
x+2=60
  -2  -2
x=58
10) 7r + 14 - 3r =30
     -14         -14
<u>7r-3r</u>=16
4r=16
÷4 ÷4
r=4
11)  m+2=6
m+2=6
     -2  -2
 m=4
m=4
÷ ÷

m=4
12) <u>2</u>(5p+9)=48
10p+18=48
      -18  -18
10p=30
÷10  ÷10
p=3
13) <u>5</u>(2x-8)=20
10x-40=20
     +40 +40
10x=60
÷10  ÷10
x=6
14)<u>6</u>(3-2x)=54
18-12x=54
-18       -18
-12x=36

Answer:
9x^2+22x-2
Step-by-step explanation:
f(g(x))=(3x+1)^2+2(3x+1)-4
       =9x^2+16x+6x+2-4
      =9x^2+22x-2
  to find the soultion of mentioned question you have to put the value of g(x) into f(x) and then solve it like normal ...
