Answer:
x = ±4 (x = 4 and x = -4)
Step-by-step explanation:
4x²-16 = x²+32

how could you classify the following shape?
A.Quadrilateral
B.Rectangle
C.Rhombus
D.Square
Answer:
Rectangle and Quadrilateral
Step-by-step explanation:
Hi,
It can't be a rhombus because, in a rhombus, all the sides are equal. The same goes for a square so those two aren't correct. It is a rectangle and in a Quadrilateral, the sides are straight. So your two answers are a rectangle and a Quadrilateral.

Name the minor arc and find its measure.
Answer: Choice B
[tex]\overset\frown{AB} ; \ 115[/tex]
=================================================
Explanation:
The measure of any minor arc is always less than 180 degrees. So it will have a smaller measure than a semicircle. Arc ADB is over 180 degrees, so we can rule that out. Minor arc AB is the measure from A to B following the shorter path along the circle, which would be 115 degrees (the longer path would be 360-115 = 245 degrees)
In other words, the central angle ACB is equal in measure to minor arc AB. Both describe the same basic idea when it comes to circles and their angle measures.

Median = 3500
Step-by-step explanation:
Data Set: 1850, 3500, 4200, 2310, 4260
=> Let's set this to the ascending order (least to greatest) first:
1850, 2310, 3500, 4200, 4260
=> Now as you cancel out the first value, cancel out the last one, and do this until u reach down to only one number:
So our median = 3500

A car drives 215 km east and then 45 km north. What is the magnitude of the car's displacement? Round your answer to the nearest whole number. km
Answer:
220 km
Step-by-step explanation:
Since the direction north is perpendicular to the direction east, the driver has covered the two legs of a right triangle. The hypotenuse is his displacement for the combination of the two segments.
D = √(215² + 45²)
= √(46,225 + 2,025)
= √48,250 = 219.6588... km
Nearest whole number: 220 km

Leona tracks her calories burned while boxing. The number of calories she burns is expressed by the function c(t) = 425t, where t is the number of hours spent boxing.
To burn more calories, Leona wears heavier gloves while boxing. The number of calories she burns while wearing heavier gloves is expressed by the function b(c) = 1.1c, where c is the number of calories burned while boxing without heavy gloves.
Which of the following composite functions expresses the calories, as a function of time, that Leona burns while boxing with heavy gloves?
c[b(t)] = 467.5t
c[b(t)] = 426.1t
b[c(t)] = 467.5t
b[c(t)] = 426.1t
Answer:
C. b[c(t)] = 467.5t
Step-by-step explanation:
No step-by-step explanation, nobody pays attention to them anyway.

You have 12 cards numbered as follows: 2,5,8,10,12,15,18,20,10,7,9,11. What is the probability of choosing an even number, given that it is a multiple of 5?
a. 5/12
b. 7/12
c. 1/2
d. 3/5
Answer:
7/12
Step-by-step explanation:
Simple:
There are 12 numbers in all and only 7 even numbers
Since there are 7 even numbers the probability of rolling an even number is 7/12.
This means that there are 7 outcomes of an even number
Therefore the probability of choosing an even number
=7/12
