Answer:
65
Step-by-step explanation:
right angle triangle so:
a=??, b=72 and c=97
a^2+b^2=c^2
a=√c^2-b^2
a=√97^2-72^2 =65
Hello!
To solve for x in algebraic equations, we need to use SADMEP. SADMEP is only used to solve these equation, and our goal is to isolate x. SADMEP is known as: subtraction, addition, division, multiplication, exponents and parentheses.
4x + 8 = 2x + 7 + 2x - 20 (simplify alike terms)
4x + 8 = 4x - 13 (subtract 8 from both sides)
4x = 4x - 21 (subtract 4x from both sides)
0 = -21
This equation has no solutions because 0 is not equal to -21, and is identified as neither because it has no real solutions.
Answer:
-89 is rational
√101 is irrational
Step-by-step explanation:
An irrational number is a number that <u>cannot</u> be expressed as a fraction in terms of whole numbers.
-89 = -89/1 which is a fraction and is therefore rational
√101 does cannot be put into a fraction of whole numbers and is therefore irrational
Answer:
I have graphed them on desmos and given you three options to choose from:
Step-by-step explanation:
1. with lines (complete shape)
2. with lines (incomplete shape)
3. without lines
Hope this helps!
well, bearing in mind that standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
so hmmm we have a fraction.... so let's multiply both sides by the LCD of all fractions to do away with denominators, hmmm say the LCD will just be 3, so we'll multiply both sides by that
