5 (a-6)(a-6)
5(a-6)^2
s2 - 256
s2 - 16^2
(s+16) (s-16)
Answer:
Step-by-step explanation:
a² - 12a + 36 = a² + 2*a *6 + 6²
Compare with (x -y)² = x²- 2ab + y²
= (a - 6)²
5a² - 60a + 180 = 5 *a² - 5 * 12 * a + 5 * 36
= 5 (a² - 12a + 36)
= 5 (a - 6)²
256 = 16 * 16 = 16²
a² - b² = (a + b)(a - b)
s² - 256 = s² - 16²
= (s + 16) (s - 16)

If a person walks 2.3 miles in 10 minutes, how far can he walk in 1.5 hours?
Answers
If a person walks 2.4 miles in 10 minutes, how far can he walk in 1.5 hours?
---------------
1.5 hours = 90 minutes
That's 9x the time, so the person will walk 9x the distance.
2.4*9 = 21.6 miles.

5x=11-16
5x=-5
x=-1
Answer:
x = -1
Step-by-step explanation:
2(2.5x + 8) = 11
Divide both sides by
2.5x + 8 = 5.5
Subtract 8 from both sides
2.5x = -2.5

Find x. (Finding an angle measure given extended triangles) Please help. Thanks!
Answers
Answer:
x = 31º
Step-by-step explanation:
The verticle angle at the bottom left is 33º
The supplementary angle on the bottom right is 180 - 98 = 82
Sum of the angles in a triangle is 180
(34 + x) + 33 + 82 = 180
Combine like terms
x + 149 = 180
Subtract 149 from both sides
x = 31º
Answer:
x = 31º
The verticle angle at the bottom left is 33º
The supplementary angle on the bottom right is 180 - 98 = 82
Sum of the angles in a triangle is 180
(34 + x) + 33 + 82 = 180
Combine like terms
x + 149 = 180
Subtract 149 from both sides
x = 31º

At a game booth, a student gets a box of candy as the prize for winning a game. The boxes come in four colors: white, red, green, and blue. There are 10 boxes of each color. All the boxes are equally likely to be given away as prizes. Which expression shows the probability of the first winner receiving a white box and the second winner also receiving a box of the same color? (1 point)
Select one:
a. (10/40) * (9/39)
b. (10/40) * (10/39)
c. (10/40) + (9/39)
d. (10/40) + (10/39)
Answers
Answer:
a. (10/40) * (9/39)
Step-by-step explanation:
Since, the total number of white box = 10,
Red box = 10,
Green box = 10,
And, Blue box = 10,
Thus, the total number of boxes = 10 + 10 + 10 + 10 = 40
The probability of receiving white box by first winner = White box / Total box = 10/40
Since, the replacing is not allowed ( Because, here boxes are allotted )
Thus, the remaining white box = 10 - 1 = 9,
And, the remaining total boxes = 40 - 1 = 39,
Thus, the probability of receiving white box by second winner = Remaining white box / Remaining total box = 9/39
Hence, the probability of the first winner receiving a white box and the second winner also receiving a box of the same color = 10/40 * 9/39
Which is required expression.
A book club wants to raise $5,000 during a dinner fundraiser. The club members have sold 323 adult dinners at $10.75 each. The cost of a child dinner is $5.50. How many child dinners will they need to sell to reach their target amount?
Answers
Answer:
13
step-by-step explanation:
divide the cost of the total of sodas you bought by the cost of one soda, for example:
$24.57 divided by $1.89 is 13 which means you bought 13 sod
Step-by-step explanation:
Money earned from adult dinners = 323 x 10.75 = $3472.25
Money required to reach target amount = 5000 - 3472.25 = $1527.75
No. of child dinners required to reach the target amount = 1527.75 / 5.50 = $277.8
Therefore, 278 child dinners are needed to reach their target amount

A rectangular certificate has an area of 54 square inches. Its perimeter is 30 inches. What are the dimensions of the certificate?
Answers
Answer:
9x4 and 9+9+6+6
Step-by-step explanation:
9x4=54
A=54 in.
P=30 in.
9+9+6+6=30
given: perimeter is 30 inches. P = 2x + 2y
and area is 54 square inches A = xy
therefore 2x + 2y = 30 & xy = 54
solving for x, put y in respect to x, by dividing both sides of xy = 54 by x. y = 54/x
substitute the y value in 2x + 2y = 30
2x + 2(54/x) = 30
multiply the value of 2(54/x) = 108/x
2x + 108/x = 30
add the two terms on the left side with a common denominator of x and multiply both sides by x
2x² + 108 = 30x ==> x² - 15x + 54 = 0 (divide each term by 2 and subtract 15x from both sides)
(x - 9)(x - 6) = 0 (factor the left side of the equation)
x = 9 or x = 6 answer for one side of the certificate.
Now find the y value.
y = 54/x therefore when x = 9 then y = 6
or when x = 6 then y = 9.
the dimensions of the certificate is 9” by 6”
