Answer:
98.4
Step-by-step explanation:using the square pyramid sa formula substitute the values
Short Answer x = - 6
Remark
You gave the second best answer.
The trick here is not to divide both sides by 2. Solve the problem this way.
log_5(x + 1)^2 = 2 Take the antilog of both sides
(x + 1)^2 = 5^2 Expand the equation
x^2 + 2x + 1 = 25 Subtract 25 from both sides.
x^2 + 2x - 24 = 0 Factor
(x + 6)(x - 4) = 0 Find the zeros.
x + 6 = 0
x = - 6 <<<<<<<< Answer. This is the extraneous root.
The reason this is an extraneous root is that x<=0 do not have a logarithem
x - 4 = 0
x = 4 This is a legitimate result to the original equation.
Check the picture below.
keeping in mind that the diagonals in a rhombus always meet at right-angles, thus all angles at point O are all right-angles.
now, notice that the AC angle bisector, cuts the angle at A in two equal halves, and if you look at the triangle BOC, there is a 15.5° angle, and a right-angle, and well, you already know what the last one is.
(-10,-13) is the answer to ur question
Answer:
287.94 (c)
Step-by-step explanation:
So first we calculate the cost of the game system after tax is added:
$299 × 1.07= $319.93
$319.93 IS THE PRICE OF THE GAME SYSTEM AFTER TAX IS ADDED.
Then we calculate the price after discount:
$319.93×0.90= $287.937
Even though the aswer isn't exact whe rounded off the answer is $287.94.
SO THE FINAL ANSWER IS $287.94.
