Answer:
Nickle and quarter.
Step-by-step explanation:
Because a quarter and penny add up to 26
56-26 = 30
a quarter and a nickle add up to 30:
25 +5 = 30
Answer:
H=44
C=87
Step-by-step explanation:
1.8 (C) + 3.00 (H) = 288.6
C= 2H-1
1.8 (2H-1) + 3 (H) = 288.6
3.6 H -1.8 + 3 H = 288.6
6.6 H = 290.4
H= 290.4/6.6 = 44
C=87

By the quadratic formula, the <em>solution</em> set of the <em>quadratic</em> equation is formed by two <em>real</em> roots: x₁ = 0 and x₂ = - 12.
<h3>How to find the solution of quadratic equation</h3>
Herein we have a <em>quadratic</em> equation of the form a · m² + b · m + c = 0, whose solution set can be determined by the <em>quadratic</em> formula:
x = - [b / (2 · a)] ± [1 / (2 · a)] · √(b² - 4 · a · c) (1)
If we know that a = - 1, b = 12 and c = 0, then the solution set of the quadratic equation is:
x = - [12 / [2 · (- 1)]] ± [1 / [2 · (- 1)]] · √[12² - 4 · (- 1) · 0]
x = - 6 ± (1 / 2) · 12
x = - 6 ± 6
Then, by the quadratic formula, the <em>solution</em> set of the <em>quadratic</em> equation is formed by two <em>real</em> roots: x₁ = 0 and x₂ = - 12.
