You would have 237 feet and 3 inches
B is 1 because when you plug in they both equal 1
Answer:
-16x^2 +9
Step-by-step explanation:
To start this problem I would rearrange so that the terms with the x's come first. Making it look like this
(4x+3)(-4x+3)
Now you take the 4x and distribute it to the -4x and the 3.
-16x^2+12x This is the first part
Take the 3 and distribute it to the -4x and the 3 as well.
-12x+9
All you do now is combine the twoso you'd have
-16x^2 +12x -12x +9 Notice there are two terms that have a regular x with no exponent. This means you can combine them to simplify further.
-12x+12x=0 So you no longer have to include this term in your answer.
-16x^2+9 Would then be your final answer.
Answer:
630 .18 feet tall is the gateway arch .
Step-by-step explanation:
As given
The angle of elevation from a park bench 778 feet from the base of the Gateway Arch in St. Louis, Missouri is 39 degrees.
Now by using the trignometric property
As diagram is given below .
CB = 778 feet
AB = 0.81 × 778
AB = 630 .18 feet
Therefore the 630 .18 feet tall is the gateway arch .
Answer:
-9
Step-by-step explanation:
you put in -1 where there is an x in the equation
3(-1) + 6(-10)
-3 - 6
-9 is the answer
