-96.45
Step-by-step explanation:
You take 71.25 and add it to 25.20 because you know that he had 71.25 in is accound already but he went into debt
Answer:
y=-3x-8
Step-by-step explanation:
y=1/3x+9
slope is 1/3
perpendicular slope = m
(m)(1/3) = -1
m = -3
Point slope form
(y+2)/(x+2)=-3
y+2=-3x-6
y=-3x-8
Correct option:
<h2>
Explanation:</h2>
Given that the line we are looking for is parallel to g, then the slope of that line and g is the same, therefore:
So we can write the point-slope form of the equation of the line as follows:

Answer:
see explanation
Step-by-step explanation:
The hypotenuse is the longest side thus is (4x + 1)
The legs are 2x and (4x - 1)
Using Pythagoras' theorem, then
(4x + 1)² = (2x)² + (4x - 1)² ← expanding factors
16x² + 8x + 1 = 4x² + 16x² - 8x + 1 , that is
16x² + 8x + 1 = 20x² - 8x + 1 ( subtract 20x² - 8x + 1 from both sides )
- 4x² + 16x = 0 ( multiply through by - 1 )
4x² - 16x = 0 ← factor out 4x from each term
4x(x - 4) = 0
Equate each factor to zero and solve for x
4x = 0 ⇒ x = 0
x - 4 = 0 ⇒ x = 4
Now x > 0, thus x = 4
2x = 2(4) = 8
4x - 1 = 4(4) - 1 = 16 - 1 = 15
4x + 1 = 4(4) + 1 = 16 + 1 = 17
Thus
perimeter = 8 + 15 + 17 = 40 cm
