10x+25 (expressions don't have equal signs)
Answer:
Step-by-step explanation:
Our equations are

Let us understand the term Discriminant of a quadratic equation and its properties
Discriminant is denoted by D and its formula is

Where
a= the coefficient of the 
b= the coefficient of 
c = constant term
Properties of D: If D
i) D=0 , One real root
ii) D>0 , Two real roots
iii) D<0 , no real root
Hence in the given quadratic equations , we will find the values of D Discriminant and evaluate our answer accordingly .
Let us start with

Hence we have two real roots for this equation.


Hence we do not have any real root for this quadratic

Hence D>0 and thus we have two real roots for this equation.

Hence we have one real root to this quadratic equation.

Answer:
A. 16°
Step-by-step explanation:
Angle E corresponds to angle N, the third angle in ∆MNO. Its measure is ...
∠N = 180° -∠M -∠O
∠N = 180° -99° -65°
∠N = ∠E = 16°
Circumference is 40 in and area is 150 in²
Step-by-step explanation:
- Step 1: Find the circumference of the circle when radius = 7 in
Circumference = 2πr = 2 × 22/7 × 7 = 44 in ≈ 40 in
- Step 2: Find the area of the circle.
Area = πr² = 22/7 × 7² = 154 in² ≈ 150 in²
