3x^2+11x-4=10x-1
3x^2+11x-10x-4+1=0
3x^2+x-3=0
Δ=1^1-4*3*(-3)=1+36=37
x1=(-1+V37)/6
x2=( -1-V37)/6
<em><u>The equivalent expressions are:</u></em>

<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>

We have to find the equivalent expressions
By distributive property,
a(b + c) = ab + ac
Therefore,

Thus equivalent expressions are found
Answer:
1386 square units
Step-by-step explanation:
Area of a cirlce = Pi x r^2 [ Pi is 22/7 as stated in question]
22/7 x 21^2 = 1386 sq. units
The answer is B. If you take the even root of a positive number, you'll get two solutions, a positive and a negative
