Answer: The answer to this question is (2a-5)(2a+5)
Step-by-step explanation:
- Because first, you have to write the quadratic equation 4a^2-25 in exponential form
- Then, you calculate the product by multiplying the terms with equal exponents by multiplying their bases
(2a)^2-5^2
- And then last but not least, using a^2-b^2=(a-b)(a+b), factor the expression
(2a-5)(2a+5) and then there's your answer and your explanation!!!!!
Answer:
$740.00
Step-by-step explanation:
85% of x is 629
Translate into algebra. Use a decimal in place of the percent:
.85x = 629
Divide by .85
x = 740
This answer makes sense because the regular price should be a little higher than the sale price. If they are paying 85% they're only getting 15% off.
Check:
740×.85 = 629

Answer:
x = 21
Step-by-step explanation:
3x - 23 = 40
Collect like terms
3x = 40 + 23
3x = 63
Divide through by 3
3x/3 = 63/3
x = 21
Check
3x - 23 = 40
since x = 21
3(21) - 23 = 40
63 - 23 = 40
40 = 40
