Answer:
m=-24
Step-by-step explanation:
Subtract 12 on both sides
m + 12 - 12 = -12 - 12
m = -24
Answer:
B.
Step-by-step explanation:
The range is all real numbers
It will indefinitely go up and indefinitely go down
4. figure A is a trapezoid the parallel sides are the bases and the other sides are the legs.
5. sum of interior angles is 360 to find the other answer subtract all known angles from 360.
6. figure B is a parallelogram. if angles are congruent that means they have the same measure. so if angle 1 is 128 then and 4 is 128.
7. the definition of a square : all interior angles each measure 90 degrees.
8. nonconsecutive means they aren't next to each other so in figure D angles d and b and angles a and c for figure E angle j and m and angle n and l
9. figure e is concave that means its got an angle that "caves in"
Here a right angled triangle given. We know that one angle of a right angled triangle is 90°.
As the sum of three angles of a triangle is 180°, so we can say the sum of other two angles of a right angled triangle is (180-90)° = 90°.
Here in the figure the other two angles given and . Sum of these two angles is 90°.
So we can write the equation as,
We have to remove the parenthesis now.
Now we will add the like terms. Here x and 2x are like terms. By adding them we will get,
To solve it for x, now we have to move 15 to the other side by subtracting it from both sides.
Now to get x, we have to move 3 to the other side, by dividing it to both sides.
We have got the required value of x.
The solution is x= 25.
