(3x-4)(x+7)-1/4x^2 as a trinomial in standard form. If you can pls provided step by step explanation
The trinomial in standard form is 11/4x² + 17x - 28
How to rewrite the expression?The expression is given as:
(3x-4)(x+7)-1/4x^2
Rewrite properly as:
(3x - 4)(x + 7) - 1/4x²
Expand the expression
3x² - 4x + 21x - 28 - 1/4x²
Collect like terms
- 1/4x² + 3x² - 4x + 21x - 28
Evaluate the like terms
11/4x² + 17x - 28
Hence, the trinomial in standard form is 11/4x² + 17x - 28

At the time that a 55 foot tall tree casts a shadow that is 32 feet long, a nearby woman is 5.5 feet tall. Which measure is the closest to the length of the shadow she will cast?
Answer:
3.2ft long shadow
Step-by-step explanation:
In this problem we are given a ratio between the tree/shadow and woman/shadow therefore we are given 3 values and 1 unknown then we can use the Rule of Three to calculate the length of the shadow which we will refer to as x. The Rule of Three simply multiplies the diagonal values and divides by the third value in order to get the missing unknown like so...
55ft tall <======> 32ft long shadow
5.5ft tall <======> x ft long shadow
(5.5 * 32) / 55 = 3.2ft long shadow
Finally, we can see that the woman's shadow would be a 3.2ft long shadow

Nathan is using his grandmother's recipe to make pies
On Monday, he used 15 3/4 cups of sugar to make 9 pies
On Tuesday, he used 23 3/4 cups of sugar to make 13 pies
Which of the following must be true? (Select all that apply)
A) He used 1 cup of sugar for every 1 3/4 pies he made
B) He would use 14 cups of sugar to make 8 pies
C) The number of cups of sugar is proportional to the number of pies he made because he used the same number of cups of sugar for each pie
D) The number of cups of sugar is not porptional to the number of pies he made because the increase in the number of cups of sugar between Monday and Tuesday is greater than the increase in the number of pies
E) if Nathan uses 8 3/4 cups of sugar to make 5 pies on Wednesday and then graphs the points, for all the three days, to represent the relationship between the cups of sugar used and the number of pies made, the points would not fall on a straight line

∠A is complementary to ∠B. The measure of ∠A is (8x+12)∘. The measure of ∠B is half the measure of ∠A.
Write an equation that can be used to determine the value of x. Then solve for x.
The equation that can be used to solve for x is 8x + 12 + 4x + 6 = 90.
The value of x is 6.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
∠A and ∠B are complementary.
This means,
∠A + ∠B = 90
Now,
∠A = 8x + 12
∠B = (8x + 12)/2 = 4x + 6
Now,
8x + 12 + 4x + 6 = 90
12x + 18 = 90
12x = 90 - 18
12x = 72
x = 72/12
x = 6
Thus,
The value of x is 6.

What is the distance between point (3,2) and line y=1/4x-9
Answer:

Step-by-step explanation:
y = [tex]\frac{1}{4}[/tex] x - 9
y - 2 = - 4(x - 3)
y = - 4x + 14
- 4x + 14 = [tex]\frac{1}{4}[/tex] x - 9
