Answer:
(x, y) = ( 1/2, -3 )
Step-by-step explanation:
y = -3
3/2 - 1 - x + y = - 3
3/2 - 1 - x - 3 = - 3
x = 1/2
solution : (x , y ) = ( 1/2, -3)
here we are gonna see why is that answer :
-3 = 3/2 -1 - 1/2 - 3 = -3
-3 = -3 = -3
i hope this helps
Answer:
7.25cm
Step-by-step explanation:
Let the complete question be;
<em>Jill cuts a piece of cardboard in the shape of a trapezoid. The area of the is 43.5sp cm. If bases are 3.5cm and 8.5cm long, what is the height.</em>
<em />
Area of a trapezoid = 1/2(a+b)*h
a and b are the parallel sides (bases)
h is the height
Given
a = 3.5cm
b = 8.5cm
A = 43.5 sq.cm
Required
Height h
Substitute the given values into the expression
Area of a trapezoid = 1/2(a+b)*h
43.5 = 1/2(3.5+8.5)*h
43.5 = 1/2 * 12h
43.5 = 6h
h = 43.5/6
h = 7.25cm
Hence the height is 7.25cm
Answer:
x³ - 5x² + 4x
Step-by-step explanation:
Given
x(x - 4)(x - 1) ← expand (x - 4)(x - 1) using FOIL
= x(x² - x - 4x + 4)
= x(x² - 5x + 4) ← distribute
= x³ - 5x² + 4x
