Answer:
x² - 10 + 2x = 2x + 90
x² - 10 + 2x - 2x = 2x - 2x + 90
x² - 10 = 90
x² - 10 + 10 = 90 + 10
x² = 100
square root them both and you get x = 10

Answer:
Option D
Step-by-step explanation:
McKenzie wants to put the soil in a box with the soil height = (10 - 2) inches
(As she plans to keep 2 inches from the top of the box empty)
Length of the box = 8 inches
Width of the box = 12 inches
Since, soil in the box will get the dimensions same as of the box but the height will be 2 inches less than the box height.
Therefore, volume of the soil = Length × Width × height
V = 8 × 12 × (10 - 2)
Option D will be the answer.

: Y = 1/3x - 1
:
M = y2 - y1/ x2-x1
M = 6 - (-3) / 1 - (-2)
Y = 1/3x + b
Then substitute one of the points into the equation
-2= 1/3(-3) + b
-2 + 2 + b = 1/3(-3) +b - b + 2
-b = 1/3(-3) + 2
-b = 1
b = -1
Y = 1/3x - 1

A bakery recorded the number of muffins and bagels it sold for a seven day period. For the data presented, what does the value of 51 summarize?
A) mean of bagels
B) mean of muffins
C) range of bagels
D) range of muffins
Answer:
Mean of bagel
Step-by-step explanation:
Working out each of the statically summaries Given in the option :
Mean of muffin :
Mean = Σx / n
n = sample size
(61 + 20 + 32 + 58 + 62 + 61 + 56) / 7
= 350 / 7
= 50
Mean of bagel :
Mean = Σx / n
n = sample size
(34 + 45 + 43 + 42 + 46 + 72 + 75) / 7
= 357 / 7
= 51
Hence, from the result obtained, we could see that the value of 51 summarizes the mean of bagel.

24. Woodworking A birdhouse has a square base with
side length 3x - 4. What polynomial in standard
form represents the area of the base?
Answer:
9x² - 24x + 16
Step-by-step explanation:
Formula for the area of the square base = s²
Where,
s = side length = 3x - 4
Therefore:
Area of the base = (3x - 4)²
Expand
(3x - 4)(3x - 4)
3x(3x - 4) -4(3x - 4)
Apply the distributive property
9x² - 12x - 12x + 16
Add like terms
9x² - 24x + 16
Area of the base in standard form = 9x² - 24x + 16
Answer:
9x^2 -24x +16 units^2
Step-by-step explanation:
(3x-4)^2 = 9x^2 -24x +16
