Answer:
68< t < 77
Step-by-step explanation:
The temperature must be between 68 and 77
68< t < 77
We are given the expression x³ - 2y² - 3x³ + z⁴. We have to evaluate it at a given set of x, y, and z values. Before then, let's combine like terms.
x³ - 2y² - 3x³ + z⁴
= -2x³ - 2y² + z⁴ <-- by combining like terms
Now we evaluate for x=3 y=5 z = -3
= -2(3³) - 2(5²) + (-3⁴) <-- by putting in for x, y, z
= -2(27) - 2(25) + 81 <--- parentheses and exponents first in order of operations
= -54 - 50 + 81 <---- multiplication is next
= -4 + 81
= 77
Thus, we evaluate and it's 77.
formula for interior angles of a polygon is 180 times the number of sides minus 2
20 a 20gon has 20 sides, 20 -2 = 18, 180*18 = 3240
sum of interior angles = 3240 degrees

<span>We know that 4 balls will make 8 caps. Than x balls will make 6 caps. We will use the proportion: 4 / 8 = x / 6. After that we will cross multiply: 8 x = 6 * 4, 8 x = 24, x = 24 : 8, x = 3. Answer: 3 balls of wills will make 6 knitted caps. I hope that my answer is helpful! Let me know if you need something more :)</span>
