D. centimeters (cm)
km is too large of a unit for this measurement, kg is a unit of weight not distance, mm is small but you'd rather choose cm
Answer:
One ounce = one- sixteen pound
5 pounds
Step-by-step explanation:
80/16=5 pounds
Answer:
previous balance
Step-by-step explanation:
Ok so firstly the answer is: 361
but here is a arw by step solution
3(7+4)^2-14/7
add 7 and 4 to get 11
3 x 11^2 - 14/7
calculate 11 to the power of 2 (121)
3 x 121 - 14/7
multiply 3 and 121 to get 363
363 - 14/7
divide 14 by 7 to get 2
363-2
subtract the two and you get 361
Hey there!
<u>Use the quadratic formula to find the solution(s). x² + 2x - 8 = 0</u>
x = -4 or x = 2 ✅
<em><u>Quadratic</u></em><em><u> </u></em><em><u>formula </u></em><em><u>:</u></em><em><u> </u></em>ax² + bx + c = 0 where a ≠ 0
The number of real-number solutions <em>(roots)</em> is determined by the discriminant (b² - 4ac) :
- If b² - 4ac > 0 , There are 2 real-number solutions
- If b² - 4ac = 0 , There is 1 real-number solution.
- If b² - 4ac < 0 , There is no real-number solution.
The <em><u>roots</u></em> of the equation are determined by the following calculation:
Here, we have :
1) <u>Calculate </u><u>the </u><u>discrim</u><u>i</u><u>n</u><u>ant</u><u> </u><u>:</u>
b² - 4ac ⇔ 2² - 4(1)(-8) ⇔ 4 - (-32) ⇔ 36
b² - 4ac = 36 > 0 ; The equation admits two real-number solutions
2) <u>Calculate </u><u>the </u><u>roots </u><u>of </u><u>the </u><u>equation</u><u>:</u>
▪️ (1)
▪️ (2)
>> Therefore, your answers are x = -4 or x = 2.
