Answer:
17 in.
Step-by-step explanation:
There are two same angles shown, so two sides are equal. We can form an equation x+4=4x+1. Solution is x=1, then both unknown sides are 5 in. long. Given all side lengths we add them 7+5+5+15 getting the perimeter.
Answer:
The discriminant is 0.
Step-by-step explanation:
we know that
In a quadratic equation of the form
The discriminant is equal to
If D=0 -----> The equation has only one real solution
If D>0 ----> The equation has two real solutions
If D<0 ----> The equation has complex solutions
In this problem
If the equation has only one intercept (x=6)
then
The equation has only one real solution
therefore
The discriminant is 0.
Answer: 12.5
Step-by-step explanation:1.50*5=7.5
7.5-70=62.5
62.5 divided by 5 = 12.5
Answer:
32
Step-by-step explanation:
Solve for x:
- Apply the distributive property: -2x + -6 = -22
- Simplify: -2x - 6 = -22
- Add 6 to each side, so it now looks like this: -2x = -16
- Divide each side by -2 to cancel out the -2 next to x. It should now look like this: x = 8
Apply the value of x to 4x:
- 4x = 4(8)
- 4(8) = 4 × 8
- 4 × 8 = 32
I hope this helps!
