Answer:
w = 10
Step-by-step explanation:
3w = 30
Divide each side by 3
3w/3 = 30/3
w = 10
Answer:
Step-by-step explanation:
If the discriminant b^2 - 4ac > 0, then the two solutions are
, and in both cases, the value on the square root is > 0, so the result will always be a real number.
"If a=b and b=c, then a=c" is a statement of the transitive property of equality. The same property applies to the congruence relation.
Your appropriate choice is
• transitive property
Answer: I don't know
Step-by-step explanation: Jk, the answer is X = 3 or 1/3
/ = Fraction
^ = Power-of
* = Multiply
Move all the terms to the left then multiply the parentheses:
(5x+3) (10-2) - (7x) * (8x) = 0
(50x^2-10x+30x-6)-7x*88x
Then multiply variables:
(50x^2-10x+30x-6)-56x^=0
Now add all the numbers together:
6x^2+20x-6=0
= 256x
Use the following formula:
x1=−b−Δ√2a
x2=−b+Δ√2a
Set up the problem:
√ =√256=16
Part 1: -20-16/2x-6 = -36/-12 = 3
Part 2: -20+16/2x-6 = -4/-12 = 1/3
5/4 would be your answer.
