The correct expression for "five times the sum of b and two" is determined by understanding the order of operations.
To represent "five times the sum of b and two" in an algebraic expression, we need to consider the order of operations. The phrase "the sum of b and two" indicates that we need to add b and two together first.
The correct expression is given by option c. (b + 2) * 5. This expression represents the sum of b and two inside the parentheses, which is then multiplied by five.
Option a, 5(b + 2), implies that only the variable b is multiplied by five, without including the constant term two.
Option b, 5b - 2, represents five times the variable b minus two, which is different from the given expression.
Option d is not provided, so it is not applicable in this case.
Therefore, the correct expression is c. (b + 2) * 5, which means five times the sum of b and two.

Write an equation of the line perpendicular to the given line that contains P.
Step-by-step explanation:
As the required line is perpendicular to y = (1/2)x + 5, product of slope of y = (1/2)x + 5 and required line should be - 1.
=> (1/2)m = - 1
=> m = - 2
Thus, required line is
=> y - (-8) = (-2)(x - 3)
=> y + 8 = -2(x - 3)

a2−12a+35
The middle number is -12 and the last number is 35.
Factoring means we want something like
(a+_)(a+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -12
Multiply together to get 35
Can you think of the two numbers?
Try -5 and -7:
-5+-7 = -12
-5*-7 = 35
Fill in the blanks in
(a+_)(a+_)
with -5 and -7 to get...

Find mzw.

Need help
Answer:
∠ W = 51°
Step-by-step explanation:
Since WX is the diameter , then
∠ WYX = 90° ( angle in a semicircle )
The sum of the 3 angles in a triangle = 180° , then
x + x + 12 + 90 = 180
2x + 102 = 180 ( subtract 102 from both sides )
2x = 78 ( divide both sides by 2 )
x = 39
Then
∠ W = x + 12 = 39 + 12 = 51°

Which of the following represents the function f(x) = 5x^(2) + 20x + 25 in vertex form. Identify the vertex.
The function f(x) = 5x^2 + 20x + 25 can be rewritten in vertex form as f(x) = 5(x + 2)^2 + 5, and its vertex is located at (-2, 5).
To rewrite the function f(x) = 5x^2 + 20x + 25 in vertex form, we complete the square. The vertex form of a quadratic function is given by f(x) = a(x - h)^2 + k, where (h, k) represents the vertex.
Let's complete the square:
f(x) = 5(x^2 + 4x) + 25
To complete the square, we need to add and subtract (4/2)^2 = 4 to the expression inside the parentheses:
f(x) = 5(x^2 + 4x + 4 - 4) + 25
Rearranging the terms:
f(x) = 5((x^2 + 4x + 4) - 4) + 25
Now we can factor the perfect square inside the parentheses:
f(x) = 5((x + 2)^2 - 4) + 25
Expanding and simplifying further:
f(x) = 5(x + 2)^2 - 20 + 25
f(x) = 5(x + 2)^2 + 5
Therefore, the function f(x) = 5x^2 + 20x + 25 in vertex form is f(x) = 5(x + 2)^2 + 5. The vertex is given by the coordinates (-2, 5).
The correct question should be :
What is the vertex form of the function f(x) = 5x^2 + 20x + 25? Identify the coordinates of the vertex.
