Answer:
<h2>C. 323 ft²</h2>
Step-by-step explanation:
1 yard = 3 feet
5yd 2ft = (5)(3)ft + 2ft = 17ft
6yd 1ft = (6)(3)ft + 1ft = 19ft
The formula of an area of a rectangle:
A = wl
w - width
l - length
Substitute w = 19ft and l = 17ft:
A = (19)(17) = 323 ft²
Answer:
Yes, because when the side lengths of a triangle are in the ratio 3: 4: 5, then it is a right triangle. These sides are 6: 8: 10, then the triangle is a right one.
Step-by-step explanation:
Answer:
(- 4, 27 )
Step-by-step explanation:
Equate the right sides of both equations, that is
x² - 2x + 3 = - 2x + 19 ← subtract - 2x + 19 from both sides
x² - 16 = 0 ← in standard form
(x - 4)(x + 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 4 = 0 ⇒ x = - 4
Substitute these values into f(x) = - 2x + 19
f(4) = - 2(4) + 19 = - 8 + 19 = 11 ⇒ (4, 11 )
f(- 4) = - 2(- 4) + 19 = 8 + 19 = 27 ⇒ (- 4, 27 )
Answer:
2x
Step-by-step explanation:
Answer:
6 units
Step-by-step explanation:
A = lw
l = w + 2
48 = lw
48 = (w + 2)w
48 = w² + 2w
0 = w² + 2w - 48
Quadratic equation results =
w = 6 or w = -8
But the measure could not be negative, therefore w = 6
