Answer:
12
Step-by-step explanation:
divide into two shapes. the first one being 2 x 4 units and the second being 2 x 2.
2 x 4 = 8
2 x 2 = 4
8 + 4 = 12
The answer is 12 square units.

Step-by-step explanation:
The values of x that will give the quadratic equation no real number solutions are -5 and 9
<h3>What are real roots of a quadratic equation?</h3>
Real roots of a quadratic equation are values of x, whose numbers can be represented on a number line.
Analysis:
We have -
+3x +c = 0
- 4ac is called the discriminant of a quadratic equation.
if - 4ac < 0, then the quadratic equation has no real root.
where a = -1, b = 3 c = c
-4(-1)c < 0
9 + 4c < 0
4c < -9
c < -9/2
Which means values lower than -9/2 would give the solution no real root.
From, the options, only -5 would give no real solution, since it is lower than -9/2.

Answer:
The correct answer is (4 , 6); (3 , 9); (0 , 6)
Step-by-step explanation:
In translation by a vector, we simply add or subtract the coordinates of a point with the vector to get the translated coordinates of the point.
Here the vector is 1 , 4.
Thus, the point E(3 , 2) would translate to ( 3+1 , 2+4) = ( 4 , 6 ).
The point F(2 , 5) would translate to ( 2+1 , 5+4) = ( 3 , 9 ).
The point G(-1 , 2) would translate to ( -1+1 , 2+4) = ( 0 , 6 ).
