Lets get started :)
2d³ + 3c² + 5
The given:
d = 4
c = 3
We substitute the given into the original!
2(4)³ + 3(3)² + 5
= 2(64) + 3(9) + 5
= 128 + 27 + 5
= 160
Answer:
The first one is an Obtuse triangle and the second is an Acute isosceles triangle :)
Step-by-step explanation:
Hope this helped!
Subtract 2x from both sides.
3y = - 2x - 12
Divide every term by 3 to get the y-variable by itself.
y = - 2/3x - 4
Since the equation is not in slope-intercept form (y = mx + b), your y-intercept is just the number in the b slot. Y-intercept is - 4 or (0, - 4).
Now to find your x-intercept, plug in 0 where the y-variable is and solve for x.
0 = - 2/3x - 4
4 = - 2/3x
Multiply both sides by - 3/2 to isolate the variable.
4(- 3/2) = x
- 12/2 = x
- 6 = x.
Your x-intercept is - 6 or (- 6, 0).
I think it’s C. 136 ft squared
