Answer:
3200
Step-by-step explanation:
3.2 ×10^3
= 3.2 × 1000
= 3200
The right answer for the question that is being asked and shown above is that: In the function f(x) = 4(x2 − 6x + ____) + 20, what number belongs in the blank to complete the square?
x2 - 6x + 9
So the answer on the blank space is 9. It should be a perfect square.
= 6/2
= 3^2
= 9
Answer:
The least common denominator would be 28.
Mutiply by 7 for 3/4.
Mutiply by 2 for 5/14.
3(7)/4(7)= 21/28, 5(2)/14(2)= 10/28
12/9÷5/20
=12/9*20/5
=4/3*4
=16/3 ans..
Answer:
128
Step-by-step explanation:
Split the shape into a triangle and a rectangle.
The base of the triangle is 12 cm.
The height of the triangle is the height of the whole shape minus the height of the rectangle, which is: 14-11=3.
We know that the formula for the area of a triangle is 0.5xbxh
Therefore, the area of the triangle is 0.5x12x3 = 18.
NOW, lets work out the area of the rectangle.
The formula for the area of the rectangle is bxh.
= 11*10
= 110.
Now you add the area of the triangle to the area of the rectangle
18+110.
= 128.
