Answer:
g(-4)= -52
Step-by-step explanation:
g(x) = 8x -20
Substitute -4 for x
g(-4) = 8(-4) -20
g(-4) = -52
Answer:
24
Step-by-step explanation:
the perimeter is all sides added up
therefore to solve for "z"
3z + 3z + 4z + 3 + 4z + 3 = 118
simplify
14z + 6 = 118
isolate z by first subtracting 6 from both sides and then dividing by 14 for both sides
z=8
plug z into side CB as AD and CB are congruent
3(8)
=24
Answer:
x = 10.3 in
Step-by-step explanation:
To find the value of a, use the area formula for a triangle. The formula is A = 1/2 *b*h. Here b = x and h= x. The formula becomes A = 1/2 *x². Substitute A = 53 and solve for x by using inverse operations.
A = 1/2x²
53 = 1/2x²
106 = x²
√106 = x
10.3 = x
Answer:
<h2>
Explanation:</h2>
In this exercise we have the following equation of a parabola:
So our goal is to find the x-intercepts. We can find this setting 
, so:
Taking 2 as common factor:
Hence this is a Non-perfect Square Trinomial. To factor out this, let's choose two numbers such that:
- The sum is -6
- The product is 5
Those two numbers are:
Because:
So this equation can be written as:
