Question 1:
(x*3)+18/8=9    is the equation
(x*3)+18=72     multiply by 8
(x*3)=54           Subtract 18
x=18                 Divide by 3

The two digit number is 18

Question 2:
x*4=43             Divide by 4
x=10.75           10 3/4
10 3/4+3 3/4     Solve

The measures of two sides of a triangle are 7.3 centimeters and 2.94 centimeters. The triangle's perimeter is 14.8 centimeters.
evablogger [386]
The perimeter is the sum of all lengths of the side of a polygon. For a triangle it is expressed as:

P = a + b + c

We let a = 7.3, b = 2.94 and c=x

Therefore, the perimeter of the given triangle is:

14.8 = 7.3 + 2.94 + x

From the options given, the correct answer is the last option. The expression, <span>x - 14.8 = 2.94 + 7.3, will give an erroneous value of the third side. It will be more than the perimeter given.</span>

If f(x)= x^2 and g(x) = 4f (x)-1 then which of the following is the value of g (-3)
Sati [7]

Answer:

<h3>27</h3>

Step-by-step explanation:

Given

f(x)= x^2-2 and g(x) = 4f (x)-1

g(x) = 4(x^2-2) - 1

g(x) = 4x²-8-1

g(x) = 4x²-9

Get g(-3):

g(-3) = 4(-3)²-9

g(-3 = 4(9) - 9

g(-3) = 36-9

g(-3) = 27
