Answer:
5
Step-by-step explanation:
First simplify 250/10= 25
square 25= 5
Hint: "4x 2 - 25 = 0" is nearly meaningless. You want 4x^2 - 25 = 0.
Note that both 4x^2 and 25 are perfect squares, so this is the difference of two squares, and is equal to (2x-5)(2x+5)= 0.
Lets solve for both possibilities.
A. (2,4)
<span>-3x+5y=2x+3y
-3(2)+5(4)=2(2)+3(4)
-6+20=4+12
14</span>≠16
Incorrect
B. (3,3)
<span>-3x+5y=2x+3y
-3(3)+5(3)=2(3)+3(3)
-9+15=6+9
6</span>≠15
Incorrect
Neither ordered pairs work for the equation.
Answer=D
Answer:
The square is the quadrilateral.
Step-by-step explanation:
A quadrilateral is a 2 dimensional geometric shape. It has four sides which may be or may not be equal.
If a quadrilateral is a square and we make its diagonal so that we get two triangles.
These two triangles are isosceles triangle as the two sides are equal and the square has four equal sides and the triangles are congruent to each other.
here, the triangles ABC and ADC are congruent and isosceles.
Answer:
x^2+11x+30
Step-by-step explanation:
This is a parallelogram.
Area of a parallelogram can be found with:
A=bh
Plug our values in.
A=(x+6)(x+5)
FOIL-
First: x*x=x^2
Outside: x*5=5x
Inside: 6*x=6x
Last: 6*5=30
x^2+5x+6x+30
Combine like terms.
x^2+11x+30
