This one is very simple.
create a simple equation to find out
15 = 12 + x
subtract 12 from each side
x= 3
the missing number is 3
or, to be even simpler, take the total, subtract the total from the number you know and the difference is the missing number.
hope I helped
ALSO, we can check going down vertically. 3 + 10 =13. this is the total listed at the bottom.
Answer:
Value of a =3
Value of b =5
Step-by-step explanation:
We are given p(1)=3 and p(2)=19
Putting x =1 to find p(1)
Now putting x=2 as p(2)=19
Solving these equations to find values of a and b
Subtract both equations
So, value of a =3
Now finding value of b bu putting value of a in equation 1
So, Value of b =5
Answer:
mathematics is the study of numbers shapes and patterns
Answer:
Step-by-step explanation:
Draw the diameter from point (-1, -5) to point (2, 3).
The triangle has base 3 and height 8.
The diameter of the semicircle is the hypotenuse of the triangle.
The radius is half the diameter.
The total area is the area of the triangle plus the area of the semicircle.
Answer:
a>4
