[tex]3^{2} + 12 = 9 + 12 = 21[/tex]
The answer is 21.
Answer:
The correct answer is 21.
Step-by-step explanation:
To solve this problem, we simply substitute 3 for a in the expression.
Given the expression,
a^2 + 12
we should replace "a" with 3, as denoted by the problem, giving us:
(3)^2 + 12
Now, we simplify using the order of operations. PEMDAS tells us that we should simplify what is in the parentheses first because it has an exponent.
9 + 12
Now, we can just add the two remaining terms together, giving us:
21
Therefore, the answer is 21.

The sum of two numbers is 55. The smaller number is 15 less than the larger number. What are the numbers?
Answer:
a=35
b=20
Step-by-step explanation:
a+b =55
a=b+15
b+15 +b =55
2b=55 - 15
2b=40
b=40 :2
b=20 (the smallest number)
a=20 +15 =35 (the largest number)
Step-by-step explanation:
55=x+15
-15 -15
40=x

What is objective ??
Answer:
In math :The objective function is a mathematical term that describes how different variables contribute to a certain value that is being sought to be optimized.
In science: Scientific objectivity is a characteristic of scientific claims, methods and results. It expresses the idea that the claims, methods and results of science are not, or should not be influenced by particular perspectives, value commitments, community bias or personal interests, to name a few relevant factors.

Write an algebraic expression for each verbal expression: 1.) The product of 5 and twice a number x, decreased by the product of 3 and that same number. 2.) Twice the sum of a number x, and another number y, increased by the product of the first number squared and 8
Answer:
1) (5 times 2x) - (3 times 2x)
2) x+y) times 2 + (x*2 times 8)
explanation:
for "times" put a multiplication sign and the astric ( * ) is for the exponent or meaning "to the power of" :)
The first equation will be formed as: [tex](5 times 2x) - (3 times 2x)[/tex]
The second equation will be performed as [tex](x + y) times\ 2 + (x*2 \ times 8)[/tex]
What is multiplication?When you take a single number and multiply it by several, you are multiplying. There are a number of distinct indications of amplification that people utilize. The "x" sign represents the most typical, however other symbols like the "*" sign are also occasionally used.
1.) The composition of 3 and that identical number, multiplied by 5, lowered by the products of 5, and double that amount will be represented as (5 times 2x) - (3 times 2x)
2.) The product of the square root of the first variable and eight times a quantity x and a quantity will be represented as (x+y) times 2 + (x*2 times 8)

How do you work out the gradient of a line?
Step-by-step explanation:
The gradient of the line = (change in y-coordinate)/(change in x-coordinate) . We can, of course, use this to find the equation of the line. Since the line crosses the y-axis when y = 3, the equation of this graph is y = ½x + 3 . To find the gradient of a curve, you must draw an accurate sketch of the curve.

Answer:
9
Step-by-step explanation:
72 flowers in 8 equal rows will have 9 flowers in each row.
__
72 = 8 × 9
Answer:
There are 9 flowers in each of the 8 rows
Step-by-step explanation:
Kevin plants a total of 72 flowers in equal rows he plants 6 rows of yellow flowers and 2 rows of red flowers how many flowers are in each row
Solution
Total flowers = 72 in Equal rows
Yellow flowers = 6 rows
Red flowers = 2 rows
Rows of yellow flowers + Rows of rec flowers = 6 + 2
= 8 rows
Flowers in each row = Total flowers / total rows
= 72 flowers / 8 rows
= 9 flowers
Flowers in each row = 9 flowers
