Can please someone help me??!!!!! Find the area of each triangle (A-D). Show your reasoning please.

Answer:

Either A= (-3,10)

OR A= (-3,-6)

Step-by-step explanation:

A = (-3,y)    B = ​(3​,2​)

(Distance from A to B) = √[(-3-3)²+(y-2)²]=10

√[36+y²-4y+4]=10

√[y²-4y+40]=10

squaring on both sides

y²-4y+40=100

y²-4y-60=0

y²-10y+6y-60=0

y(y-10) + 6 (y-10)=0

(y - 10)(y + 6)=0

Either y=10 =>A= (-3,10)

OR y=-6 =>A= (-3,-6)

Answer:

3

Step-by-step explanation:

Well first let's calculate how many times she jumped per hour. For that we need to divide 42 by 7 which is 6. Now we need to divide that by two because they are asking for every half hour, not every hour. So 6 divided by 2 is 3. So our answer is 3.

Answer: The answer would be B. 12a+6b

Answer:

0/6, 1/3, 1/6, 5/6, 1/2, 2/3, 1/2, 1/3

Hey there! :)

I believe the correct answer to your question is 12.

Find the prime factorization of 84

84 = 2 × 2 × 3 × 7

Find the prime factorization of 108

108 = 2 × 2 × 3 × 3 × 3

To find the gcf, multiply all the prime factors common to both numbers:

Therefore, GCF = 2 × 2 × 3

GCF = 12    

Hopefully this can help you out!

The answer to the question is X=18

Answer:

x = 15

Equation = x

                  __.  +4=9

                   3

Step-by-step explanation:

x = number

x

__.  + 4 =9

3

First, you subtract 4 on both sides of the equation to get x by itself.

x

__. = 5

3

Then, you multiply the denominator (3) on both sides to get x by itself

x = 15

5x+34+8x+15=88

step by step

Let's solve your equation step-by-step.

5x+34+8x+15=88

Step 1: Simplify both sides of the equation.

5x+34+8x+15=88

(5x+8x)+(34+15)=88(Combine Like Terms)

13x+49=88

13x+49=88

Step 2: Subtract 49 from both sides.

13x+49−49=88−49

13x=39

Step 3: Divide both sides by 13.

13x

13

Answer:

408 units^2

Step-by-step explanation:

area of triangle: 1/2(6)(8)=24

24*2=48

area of bottom rectangle: 6(15)=90

area of front rectangle: 15(10)=150

area of back rectangle: 8(15)=120

48+90+150+120=408

Therefore, 408 units^2

Answer:

about 9.4 units

Step-by-step explanation:

Distance formula:

√(x1 - x2)² + (y2 - y1)²

Coordinates:

A (4, 2)

B (9, 10)

Let's make 9 = x1

Let's make 4 = x2

Let's make 10 = y1

Let's make 2 = y2

Substitute into the distance formula:

√(x1 - x2)² + (y2 - y1)²

√(9 - 4)² + (2 - 10)²

Solve:

√(9 - 4)² + (2 - 10)²

√(5)² + (-8)²

√25 + 64

√89

≈ 9.4

Therefore, the length of AB is approximately 9.4 units.

Answer:

About 9.4 units

Step-by-step explanation:

To find the distance between two points

d = sqrt(( y2-y1) ^2 + (x2-x1) ^2)  where (x1,y1) and (x2,y2) are the points

   =  sqrt(( 10-2)) ^2 + (9-4) ^2)

   =  sqrt((8) ^2 + (5) ^2)

   = sqrt(64+ 25)

    = sqrt(89)

   =9.433981132

About 9.4 units

Answer:

the answer is bbbbbbb

Step-by-step explanation:

Answer:

I think the perimeter is 8 yd

Step-by-step explanation:

Because it's a square, if one side is 2 yd then we can assume that the remaining 3 sides are also 2 yd long. So, 2 yd + 2 yd + 2 yd + 2 yd =  8  yd

Answer:

Step-by-step explanation:

We can safely focus on 1/x.  The smaller x is, the greater 1/x will be.  Note that x cannot equal zero.  Here we are asked to focus on 1/10 < x < 1, in which 1/10 is obviously the smallest x value.  But 1/10 < x < 1 restricts x to numbers greater than 1/10.  The graph of y = 10 + 1/x is not defined for x = 1/10, but as we approach x = 1/10 along the graph, we see the graph approaching (but not touching) the maximum value 10 + 1/(1/10), or 20.
