hello :
<span>help :
<span>the discriminat of each quadratic equation : ax²+bx+c=0 ....(a ≠ 0) is :
Δ = b² -4ac
1 ) Δ > 0 the equation has two reals solutions : x = (-b±√Δ)/2a</span>
2 ) Δ = 0 : one solution : x = -b/2a
3 ) Δ < 0 : no reals solutions</span>
7.32 is the radius because all you have to do is reverse the formula for circumference
You will have to add your whole then multiply your fraction
I know you probably dont need this anymore but the answer is
1 = gerund
2= infinitive
3 = participle
hope i helped and good luck ;D
Answer:
Step-by-step explanation:
set it up like this
19x + 11 = 11x + 4
then self like algebra
19x + 11 -4 = 11x + 4 - 4
19x + 7 = 11x
19x -11x + 7= 11x -11x
8x ÷ 8 + 7 ÷ 8
x = 0.875
plug it into
19x + 11
19 × 0.875 + 11 = 27.625
so 27.625 should be your answer
