This question is worth 80 points can someone check my answeres
14. using a scale factor of 1inch=16 feet, what are the blueprint dimensions of a room that is 20 feet x 28 feet?
a. 1.5in. x 25 in.
b.1.25in x 2.25in
c. 1.25in x 1.75 in***
d. 1.5 in x 1.75

9. the sides of a rectangle are increased by a scale factor of 4. the perimeter of the smaller rectangle is 20 cm. what is the perimeter of the larger rectangle?
a. 320cm
b. 80cm***
c. 120 cm
d. 60cm

*** means my answer so much

Answer/Step-by-step explanation:

#14. Correct

20ft x 28ft = 560 ft

560ft divided by 16 = 35ft

1.25in x 1.75in = 2.1875

2.1875in x 16 = 35ft

#9. Correct

20cm x 4 = 80cm

Btw this doesn't give us 80 points it gives us half of that = 40 points

the answe i =−n+5

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
