Answer:

289/4

Step-by-step explanation:

x² + 17x + 12 = 0

x² + 17x = -12

Take half of the second coefficient, square it, then add the result to both sides.

(17/2)² = 289/4

x² + 17x + 289/4 = -12 + 289/4

(x + 17/2)² = 241/4

use the graph to determine the domain and range of the relation and state whether the relation is a function

Answer:

the domain is {0, 1, 2, 3, 4... to positive infinity}

The range is {-1, -3, 0, -4 and so on}

this is not a function

Step-by-step explanation:

domain is a set of all x values, so just write the x values based on the graph

range is a set of all y values, so just write y values based on the graph

not function because it doesnt satisfy with the vertical line test.

<h3>Answer:  21.4 square meters</h3>

Work Shown:

A = area of the front triangular face

A = base*height/2

A = 2*1.7/2

A = 1.7

L = lateral area

L = (perimeter of the base)*(depth)

L = (2+2+2)*(3)

L = 18

SA = total surface area of a triangular prism

SA = 2*A+L

SA = 2*1.7+18

SA = 21.4 square meters

I need help please thanks!
Natasha_Volkova [10]

Answer:

f=39

Step-by-step explanation:

hi! first, we can multiply by 12 on both sides to eliminate the 12 in the denominator.

f+3= (7/2)*12

f+3=84/2

f+3=42

now, subtract 3 on both sides.

f=39
