Use the expression 28b - 4c. Part B: What is the value of the expression when b = -4 and c = 1? Show your work or explain.

Brilliant_brown [7]

Answer:

The value of the expression is -116

Step-by-step explanation:

Given

$Expression: 28b - 4c$

Required

Solve when b = -4 and c = 1

$Expression: 28b - 4c$

Substitute -4 for b and 1 for c

$Expression: 28*-4 - 4*1$

$Expression = -28*4 - 4$

$Expression = =112 - 4$

$Expression: -116$

The value of the expression is -116

Find 3 consecutive numbers where the product of the smaller two numbers is 19 less than the square of the largest number.

Reika [66]

N; n+1; n+2 - 3 consecutive numbers

n(n + 1) = (n + 2)² - 19 |use a(b + c) = ab + ac and (a + b)² = a² + 2ab + b²

n² + n = n² + 4n + 4 - 19 |subtract n² from both sides

n = 4n - 15 |subtract 4n from both sides

-3n = -15 |divide both sides by (-3)

n = 5

n + 1 = 5 + 1 = 6

n + 2 = 5 + 2 = 7

Answer: 5; 6; 7.
