3x^2 - 11x + 10 =
This trinomial is in the form
ax^2 + bx + c.
a = 3; b = -11; c = 10
Step 1. Multiply coefficients ac.
ac = 3(10) = 30
Step 2. Find 2 factors of ac multiply to ac and add to b.
In this case, find two factors of 30 that multiply to 30 and add to -11.
-6 and -5 work since (-6)(-5) = 30 and (-6) + (-5) = -11
-6 and -5
Step 3. Break up the middle term in to a sum using the numbers from step 2.
We will break up -11x into -6x - 5x
Now we have
= 3x^2 - 6x - 5x + 10
Step 4. To factor by grouping, factor out a common factor out of the first two terms and factor out a common factor out of the last two terms.
= 3x(x - 2) - 5(x - 2)
Step 5. Factor out the common binomial.
= (x - 2)(3x - 5)

An equation is shown below: 3(4x + 5) = 12 Which of the following correctly shows the beginning steps to solve this equation? (4 points) Group of answer choices Step 1: 12x + 15 = 12 Step 2: 12x = −3 Step 1: 12x + 5 = 12 Step 2: 12x = 7 Step 1: 7x + 5 = 12 Step 2: 7x = 7 Step 1: 7x + 8 = 12 Step 2: 7x = 4
Answer:
I believe the answer would be step 1: 12x + 15 = 12, and step 2: 12x = -3.
Step-by-step explanation:
3(4x + 5) = 12, you would foil and do 3 times 4x which is 12x, then do 3 times 5 which is 15. So the result would be 12x + 15 = 12. And the step 2 that goes along with this answer. you would do -15 on both sides of the equal sign, so now you have 12x = 12 - 15 which is -3, so it would be 12x = -3
Answer:
Step 1 would be the answer: Step 1: 12x + 15 = 12 Step 2: 12x = −3 Step 1: 12x + 5 = 12

∠A and \angle B∠B are complementary angles. If m\angle A=(8x+27)^{\circ}∠A=(8x+27)
∘
and m\angle B=(6x-21)^{\circ}∠B=(6x−21)
∘
, then find the measure of \angle B∠B.
Answer:
∠ B = 15°
Step-by-step explanation:
Complementary angles sum to 90° , that is
∠ A + ∠ B = 90 , substitute values
8x + 27 + 6x - 21 = 90
14x + 6 = 90 ( subtract 6 from both sides )
14x = 84 ( divide both sides by 14 )
x = 6
Thus
∠ B = 6x - 21 = 6(6) - 21 = 36 - 21 = 15°

blThe mean height of the corn plants of variety A is 43.8 inches. Interpret the value of the mean in the
situation.
Answer:
The average inches of the height of the corn plants of variety A is 43.8 inches
Step-by-step explanation:
In mathematics or statistics, the mean refers to the average of numbers.
The mean is estimated by dividing sum of all the numbers by the count of the numbers.
For this question, the mean height of the corn plants of variety A of 43.8 inches is obtained as follows:
Sum of all the inches = 46 + 46 + 47 + 48 + 49 + 49 + 50 + 6 + 48 + 49 = 438 inches
Count of all the inches = 10
Mean = Sum of all the inches / Count of all the inches = 43.8 inches
The interpretation of this is that the average inches of the height of the corn plants of variety A is 43.8 inches.

Listen i know its dumb but-
solve for w
10 + w = -9
Answer:
w = -19
Explanation:
To solve this equation, subtract ten from both sides. This will isolate the variable (w) and allow us to find its value.
[tex]10 + w = -9\\(10 - 10) + w = (-9 - 10)\\w = (-9 - 10)\\w = -19[/tex]
If you would like to double check that the variable (w) does in fact equal negative nineteen, substitute the value of the variable in the equation and solve.
[tex]10 + w = -9\\10 + -19 = -9\\-19 = -19 [true][/tex]
Therefore, the value of w in the given equation is -19.
