You can't use distributive property by a calculator
The area of a triangle is A = (b*h)/2:
(5 * 8)/2 = 20
Answer:
-8x+21
Step-by-step explanation:
Use the distributive property.
Answer:
x+4y=-35
-8x-4y=28
Step-by-step explanation:
The answer to the original equations is (1, -9). You can solve that by using substitution by moving the 4y over and substituting that equation for x on the second part of the top equation. Using elimination, the second set of answers will give you the same, (1, -9)!
