- Addition
- Subtraction
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify.</em>
<em>x</em> = 3
<em>y</em> = 28
xy - 538y + x⁶
<u>Step 2: Evaluate</u>
- Substitute in variables: 3(28) - 538(28) + 3⁶
- [Order of Operations] Exponents: 3(28) - 538(28) + 729
- [Order of Operations] Multiply: 84 - 15064 + 729
- [Order of Operations] Subtract: -14980 + 729
- [Order of Operations] Add: -14251
Answer:
d
Step-by-step explanation:
40% = 40/100
40/100 X = 8
X = 800/40 = 20
X% of 40 = 20/100*40 = 8
I think one two and three are correct if you do the math and put the numbers in the perenthisis (x on the left, y on the right) to the equation then you will get the answer.
Answer:
x² - 10x + 16 = 0
Step-by-step explanation:
Given the solutions x = 8 and x = 2 , then the factors are
(x - 8) and (x - 2) and the equation is
(x - 8)(x - 2) = 0 ← expand left side using FOIL
x² - 10x + 16 = 0
I believe it’s 2% hope this helps!
