F(x)=x^2+9x
f(-7)=(-7)^2+9(-7)
f(-7)=49-63
f(-7)=-14
Hope this helps you..!!!
Answer:
r=4
Step-by-step explanation:
Area of a circle is
A = pi* r^2
We know the area and 3.14 = pi
50.24 = 3.14 * r^2
Divide each side by 3.14
50.24/3.14 =3.14 /3.14 *r^2
16 = r^2
Take the square root of each side
sqrt(16) = sqrt(r^2)
4 =r
Answer:
False
Step-by-step explanation:
The two triangles given in the diagram are congruent.
This means that they are equal in all respect.
The sides and the angles are all equal.
This means that m<T=80
When TR is 46 then it means 64=36, which is not True
Therefore we cannot assume that TR=46
