Answer:
1 1/4
Step-by-step explanation:
To find the distance between the points take the last point and subtract the first point
7/8 - (-3/8)
A negative negative is a positive
7/8 +3/8
10/8
8/8 + 2/8
Simplifying
1 + 1/4
1 1/4
Answer:
-6 ;
ax² + bx + c ;
-1
Step-by-step explanation:
1)
Give thequadratic equation :
4x² - 6x - 5
The values of a, b, c are the Coefficient of x², x and the constant respectively
Therefore, the value of b is the Coefficient of x = - 6
2.)
Standard form of a quadratic equation is :
ax² + bx + c
a = Coefficient of x² ; b = Coefficient of x ; c is a constant
3.)
2x² - 4x + 7
Axis of symmetry :
-b / 2a
a = 2 ; b = - 4, c = 7
-b / 2a = - 4 / 2(2)
= - 4 / 4
= - 1

Answer:
42 sq. cm
Step-by-step explanation:
Answer: 42 sq. cm
Length of Big Rectangle: 7
Width of Big Rectangle 7+0.5+0.5 = 8
Area of Big Rectangle: 56
Area of Small Rectangle = 0.5*7 = 3.5
Area of 4 Small Rectangles = 3.5 *4 = 14
Shaded Area = Big Rectangle - 4 Small Rectangles = 56 - 14 = 42 sq. cm
