Answer:
31.5cm²
Step-by-step explanation:
area of a triangle =1/2 b h
b= 7cm
h=9cm
1/2×7×9
= 1/2×63
= 31.5cm²
hypotenuse is unknown so,
c²=a²+b²
c²= 7² + 9²
= 49 + 81
c²= 130
c= 11.4cm
perimeter= 7 +9+11.4
=27.4cm
pls note that no unit was stated
F(7) means that the x value is 7, so all you have to do is substitute 7 into the equation.
f(7)=10-2(7)
or more simply,
y=10-2(7)
y=10-14
y=-4
So the answer would be -4
