Answer:
In 4 hours, Brad will travel 220 miles.
Step-by-step explanation:
Create the direct variation model-
y = kx
<em>y- represents the total miles</em>
<em>x- represents hours</em>
<em>660 = k12</em>
<em>660/12 = k</em>
<em>k = 55</em>
<em>Model:</em>
y = 55x
<em>Replace x with 4</em>:
y = 55(4)
y = 220
The answer is 220 miles.
304.85 cm²
The area (A) of a polygon is calculated as
A = pa ( p is the perimeter and a the apothem ) , thus
A = 45.5 × 6.7 = 304.85 cm²
11 m and 14 m
Legs: x and y
---
1/2xy= 77 ⇒ xy= 154
√x²+y²= √317 ⇒ x²+y²=317
x²+y²+2xy= (x+y)²= 2*154+317= 625 ⇒ x+y= √625= 25
x= 25-y
xy=154 ⇒ y(25-y)= 154 ⇒ 25y- y²=154 ⇒ y²- 25y +154=0 ⇒ y=11 and y=14
x= 25-y= 14 and 11
I would say triangle. But I am not completely sure!
Hope this helps!
should be x^2-9/x-3
