Answer:
Step-by-step explanation:
Question 1
5x+2y=21
5x+2y+−2y=21+−2y
5x=−2y+21
Step 2: Divide both sides by 5
5x/5=-2y+21/5
Answer =-2/5 y+21/5
– 2x+6y=-34
Question 2
−2x+6y=−34
Step 1: Add -6y to both sides.
−2x+6y+−6y=−34+−6y
−2x=−6y−34
Step 2: Divide both sides by -2.
-2x/-2=-6y=-34/2
x=3y+17

SA = (l x w x 2) + (l x h x 2) + (w x h x 2)
SA = (6 x 4 x 2) + (6 x 2 x 2) + (4 x 2 x 2)
SA = 48 + 24 + 16
SA = 88
The answer is 88 square units.

the answer is 264000.....
Answer:
Lets name the first set A and the second one B.
<u>The union:</u>
- A∪B = {-7,0}∪{-3,5} = {-7, -3, 0, 5}
<u>The intersection:</u>
- A∩B = {-7,0}∩{-3,5} = ∅ as no common elements
