Answer:
x= -2
Step-by-step explanation:
Step 1. In order to find the zeros of the function, we must factor it.
Step 2. To factor this, we have to find two numbers that multiply to 4 and add to 4 which is 2 ( 2*2=4 and 2+2=4)
step 3. 0=(x+2)(x+2)
Step 4 make (x+2) equal to zero and solve which gives us -2, so -2 =x.
Answer:
CB= 4
Step-by-step explanation:
the triangles are in AA similarity.
AB/AD = BC/DE
4/12 = x/12
CROSS MULTIPLY;
