For the first one it has 4 right, zero greater and zero less than. For number two is has 0 right, 2 greater than and 3 less to
Answer:
A. ~14.3 B. ~9.93
Step-by-step explanation:
A.
By looking at the equation you can see that you need to find the tan of the angle so the equation will be "Tan 40= 12/x" which you can simplify to "X=12/Tan 40" which equals "about 14.3"
B.
This one is very similar
By looking at the equation you can see that you need to find the Cos of the angle so the equation will be "Cos 25= 9/x" which you can simplify to "X=9/Cos 25" which equals "about 9.93"
Answer:
Expression for area = 3x² - 15x - 42
Step-by-step explanation:
Given that:
Length of rectangle desktop = 3(x+2) = 3x+6 units
Width of rectangle desktop = x - 7
Area of rectangle desktop = Length * Width
Area of desktop = (3x+6)(x-7)
Area = 3x(x-7) +6(x-7)
Area = 3x² - 21x + 6x - 42
Area = 3x² - 15x - 42
Hence,
Expression for area = 3x² - 15x - 42
For the first expression we will only simplify the constants:
4b - 24 + 19 ——> 4b - 5
The second expression only has variables so we simplify the whole expression
4p - 5p - 30p = -31p
The third expression we will only simplify the variables
4.2v - 5 - 6.5v ——> -2.3v - 5
The answer is 4. i put it into a calculator
