Answer:
Step-by-step explanation:
S= 2 (LW) +2 (LH) +2(WH)
then we can plug in the values we know! :)
S= 2(2*3) +2(2*4) +2(3*4)
Then we can do some simplifying
S= 2(6) +2(8) +2(12)
Then some more multiplying...
S=12 +16 +24
Then lastly, addition
S= 52 cm^2
Subtract -6 from both sides
3x^2 + 17x + 4 - (-6) = -6 - (-6)
3x^2 + 17x + 10 = 0
factor left side of equation
(3x+2)(x+5)=0
set factors to 0
x = -2/3 OR x = -5
I would go with -5
Answer:
She will walk and run 148.2 miles in a year
Step-by-step explanation:
She walks: 0.75+0.5=1.25 miles each week
And: 1.25 *52=65 miles a year
She runs : 1.6 miles a week
And: 1.6*52 =83.2 miles a year
Total miles : 83.2+65=148.2 miles
