Answer:

3x - 8

please help me with a brainiest 5star

Step-by-step explanation:

You need to substitute x-1 wherever x is appearing in the equation

f(x) = 3x-5

so;

f(x-1) = 3(x-1) - 5

= 3x - 3 - 5

= 3x - 8

Can u help me. if answer is correct, i will give u brainliest
den301095 [7]

Answer:

135 units²

Step-by-step explanation:

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height )

To calculate h use Pythagoras' identity on the right triangle on the left

h² + 8² = 17²

h² + 64 = 289 ( subtract 64 from both sides )

h² = 225 ( take the square root of both sides )

h = \sqrt{225} = 15 , thus

A = 9 × 15 = 135 units²

a^2+b^2=c^2

8.5^2+11^2=x^2
72.25+121=193.25
square root of 193.25=13.9014 or 13.9 in


9.5^2+15^2=x^2
90.25+225=315.25
