Answer: (x + 1) (x+8) is the expression [a].
Step-by-step explanation:
Given : x² + 9x + 8 .
To find :Which expression has an equivalent value to x2 + 9x + 8 for all values of x.
Solution : We have given that
x² + 9x + 8 =0
On factoring : x² + 8x +1x + 8 =0.
Taking common terms
x( x+8 ) +1( x+ 8) =0.
(x + 1) (x+8) =0
Therefore , (x + 1) (x+8) is the expression [a].

multiplying polynomials find the product (2a-1)(8a-5)
Answers
The product of (2a-1)(8a-5) is 16a² - 18a + 5.
To find the product of (2a-1)(8a-5), we can use the distributiveproperty. This means that we multiply each term in the first polynomial (2a-1) by each term in the second polynomial (8a-5) and then combine like terms.
Applying the distributive property, we have:
(2a-1)(8a-5) = 2a(8a) + 2a(-5) - 1(8a) - 1(-5)
Simplifying this expression, we get:
16a² - 10a - 8a + 5
Combining liketerms, we have:
16a² - 18a + 5
Therefore, the product of (2a-1)(8a-5) is 16a² - 18a + 5.
In this case, we multiplied each term of the first polynomial by each term of the second polynomial, resulting in four terms. Then, we combined like terms to simplify the expression. The final product is a quadratic polynomial with a leading coefficient of 16 and terms involving the variable 'a'.

Answers
Answer:
1) 5
2) 5
Step-by-step explanation:
Data provided in the question:
(3²⁷)(5¹⁰)(z) = (5⁸)(9¹⁴)()
Now,
on simplifying the above equation
⇒ (3²⁷)(5¹⁰)(z) = (5⁸)((3²)¹⁴)()
or
⇒ (3²⁷)(5¹⁰)(z) = (5⁸)(3²⁸)()
or
⇒
or
⇒
or
⇒
we can say
x = 5, y = 2 and, z = 3
Now,
(1) y is prime
since, 2 is a prime number,
we can have
x = 5
2) x is prime
since 5 is also a prime number
therefore,
x = 5
