Mathematics

Part A:

There are 25 blocks for the length, and the length of each is 5.5 inches. 5.5x25=137.5

There are 9 blocks for the height, and each is 2.75 inches. 2.75x9=24.75

Since we're trying to find how much longer the length is to the width, we find the difference. 137.5-24.75=112.75

So part A answer is <em><u>112.75 (or 112¾)</u></em>

Part B:

We know the length is 137.5 and the height is 24.75. To find how many times longer the length is, we need to divide to see how many 24.75 can go into 137.5.

137.5÷24.75=5.55

So the answer to part B is <u><em>5.55. Given the context, the answer would probably be 5, because that's how many entire height can fit.</em></u>

<u><em /></u>

Sorry if it's wrong lol

Answer:

m=0.833333

Step-by-step explanation:

(1/16)−3m+1=64

log((1/16)−3m+1)=log(64)

(Take log of both sides)

(−3m+1)*(log(1/16))=log(64)

−3m+1=log(64)

log(1/16)

−3m+1=−1.5

−3m+1−1=−1.5−1

(Subtract 1 from both sides)

−3m=−2.5

−3m

−3

=

−2.5

−3

(Divide both sides by -3)

Factor completely<br> 486+108x+6x^2<br><br> Thank you!
viktelen [127]

Answer:

6(x + 9) (x + 9)

or

6 (x+9)^{2}

Step-by-step explanation:

468 + 108x + 6x^{2} \\6x^{2} +108x + 468

Greatest common factor of 6, 108, and 486:

6 x 1 = 6

6 x 18 = 108

6 x 81 = 486

GCF: 6

so:

6(x^{2} +18x +81)

x^{2} +18x + 81

factors to:

(x + 9) (x + 9)

because:

9 x 9 = 81

9 + 9 = 18

So:

It factors completely too:

6(x + 9) (x + 9)

or

6 (x+9)^{2}

ella [17]
65+90=155 
180-155=25
180-25=155
180 because it is the angle of a straight line
180 because it is the total angle of a triangle
