To simplify this expression we first need to apply the distributive property of the product. This means that we need to multiply the number outside of the parenthesis by each term of the sum inside the parenthesis. This is done below:
The simplified expression is "-20+12w".
Answer:
1 x 31 OR 15.5 x 2
Step-by-step explanation:
As 31 is a prime number, the only whole numbers that do it are 1 × 31. There is another method using decimals. Ex: 15.5 x 2=31
Answer:
surface area≈126.65
Step-by-step explanation:
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving forA
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=5·7+5·7+5·7+1
2·﹣54+2·(5·5)2+2·(5·5)2﹣54+2·(5·5)2﹣54≈126.65064
Answer:
5
Step-by-step explanation:
10-(2+3) = 5
Plug in x = 12 and y = -5 into the given equation:-
3(12) - 3(-5) = 36 + 15 = 51 Not 21
So (12,-5) is not a solution.
