Answer:
Step-by-step explanation:
The expression (2 square root sign 27) - (3 square root sign 32) is 
.
To simplify, simplify inside the radicals by removing perfect square factors.
The expression becomes .
This cannot be simplified anymore because whats under the radical is not the same.
Solution:
we have been asked to find the product of (x+y+3)(x+y-4).
we will multiply term by term as below
Hence the the product of (x+y+3)(x+y-4) is 
Answer:
They are supplementary.
Step-by-step explanation:
If two angles form a linear pair, the angles are supplementary.
It is m4 in my opinion i’m not sure tho
Answer:
ABD= 58
BDC= 32
Step-by-step explanation:
complementary = 2 angles equal 90 degrees.
8y+2=90
Subtract 2 both sides.
8y=88
y=11
That's not all, put y into the equations.
ABD
5(11)+3
Multiply
55+3=58
BDC
3(11)-1
MULTIPLY
33-1
SUBTRACT
32
