Hi there! Solving the absolute value equation is like solving a quadratic equation.
From the absolute equation:
Cancel the absolute symbol and write plus-minus of 4.
Solve the equation for q-term.
Hence, the value of q are -2,-4

Step-by-step explanation:
B and D, they lie in the shaded area
The solution is x=8 and y = 6
Step-by-step explanation:
Given,
x+y = 14 ------ (1)
2x-2y = 4 ------- (2)
To find the solution of the given equation
Dividing both sides of (2) by 2 we get,
x-y = 2 ----(3)
Now we will solve (1) and (3)
Adding (1) and (3) we get,
(x+y) + (x-y) = 14+2
or, 2x = 16
or, x = 8
Again, putting the value of x=8 in (1) we get,
y = 14-x
= 14-8 = 6
Hence,
The solution is x=8 and y = 6
The area of a triangle formula is b×h×1/2, so 12×5a+7b is 60a+84b.
Multiply that by a half.
60a+84b × 1/2
30a+42b
