Need answers for 70-75

adoni [48]

Answer:

70. 0

71. -54

72. 12

73. 86

74. 59

Step-by-step explanation:

To evaluate an expression, substitute specific values for the variables and simplify using Order of Operations.

70. c-3d becomes

$(1)-3(\frac{1}{3}) = 1-(\frac{3}{3}) = 1-1 = 0$

71. $x+x^3-4x^4$ becomes

$2+2^3-4(2)^4 = 2+8-4(16) = 2+8-64=10-64=-54$

72. $5a+3a^2$ becomes

$5(-3)+3(-3)^2 = -15 +3(9) = -15 + 27 = 12$

73. $F=\frac{9}{5}C+32$ becomes

$F=\frac{9}{5}(30)+32=\frac{270}{5}+32 = 54+32 = 86$

74. $F=\frac{9}{5}C+32$ becomes

$F=\frac{9}{5}(15)+32=\frac{135}{5}+32 = 27+32 = 59$

Explain the process and the properties you have to use to solve the logarithmic equation: log(3)x + log(3)4 - 2 log(3)3 = 2

Akimi4 [234]

81/4

Step-by-step explanation:

$log_{3}( \frac{4x}{{3}^{2} } ) = 2$

${3}^{2} = \frac{4x}{ {3 }^{2} }$

9=4x/9

81=4×

x=81/4

adding logs means elements are multiplied, subtracting means divide. number in front of log is raised to power

base of log is raised to power of element after =

element in log is then equal to log base raised to power

solve resulting equation
