Express as a trinomial. (2x+6)(2x+8)
The value of the equation is A = 4x² + 28x + 48
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
A = ( 2x + 6 ) ( 2x + 8 ) be equation (1)
Now , on simplifying the equation , we get
A = 2x ( 2x + 8 ) + 6 ( 2x + 8 )
On further simplification , we get
A = 2x ( 2x ) + 2x ( 8 ) + 6 ( 2x ) + 6 ( 8 )
A = 4x² + 16x + 12x + 48
A = 4x² + 28x + 48
Therefore , the value of A is 4x² + 28x + 48
Hence , the equation is A = 4x² + 28x + 48

A person runs at 35 m/s from a standstill. What is their acceleration after 5 sec?
Answer:
The acceleration is 7m/s^2
Step-by-step explanation:
Given
[tex]u = 0m/s[/tex] -- Initial Velocity
It is 0 because the person starts from a standstill
[tex]v = 35m/s[/tex] -- final velocity
[tex]t = 5s[/tex] -- time
Required
Determine the acceleration
This is calculated using Newton's first equation of motion
[tex]v = u + at[/tex]
Substitute values for v, u and t
[tex]35 = 0 + a*5[/tex]
[tex]35 = 0 + 5a[/tex]
[tex]35 = 5a[/tex]
Divide both sides by 5
[tex]\frac{35}{5} = a[/tex]
[tex]7 = a[/tex]
[tex]a = 7[/tex]
Hence, the acceleration is 7m/s^2

4. Find CD and X . (3 points) x ^ 3 + 20 30 D x ^ 8 + 22x - 120 will mark brainliest
Answer:
CD = 15
x = 5
Step-by-step explanation:
Since BF ≅ FD and AE ≅ EC, then [tex]EF = \frac{AB + CD}{2}[/tex]
So, [tex]30 = \frac{x^{2} +20 + x^{2} + 22x - 120}{2}[/tex]
[tex]60 = 2x^{2} + 22x - 100[/tex]
[tex]2x^{2} + 22x - 160 = 0[/tex]
[tex]2(x^{2} + 11x - 80) = 0[/tex]
2(x - 5)(x + 16) = 0
x = 5 or x = -16
If x = 5, then CD = [tex]5^{2} +22(5) - 120 = 25 + 110 - 120 = 15[/tex]
Ix x = -16, then CD = will be a negative number which it cannot be.

which expression is equivalent to x^6 - 16x^2?
Answer:
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 16 is the square of 4
Check : x4 is the square of x2
Factorization is : (x2 + 4) • (x2 - 4)
Equivalent expressions are expressions with equal values
The equivalent expression of [tex]\mathbf{x^6 - 16x^2}[/tex] is [tex]\mathbf{x^2(x + 2)(x - 2)(x^2 + 4)}[/tex]
The expression is given as:
[tex]\mathbf{x^6 - 16x^2}[/tex]
Factor out x^2
[tex]\mathbf{x^6 - 16x^2 = x^2(x^4 - 16)}[/tex]
Express x^4 as (x^2)^2
[tex]\mathbf{x^6 - 16x^2 = x^2((x^2)^2 - 16)}[/tex]
Express 16 as 4^2
[tex]\mathbf{x^6 - 16x^2 = x^2((x^2)^2 - 4^2)}[/tex]
Apply difference of two squares
[tex]\mathbf{x^6 - 16x^2 = x^2((x^2 - 4)(x^2 + 4))}[/tex]
Express 4 as 2^2
[tex]\mathbf{x^6 - 16x^2 = x^2((x^2 - 2^2)(x^2 + 4))}[/tex]
Apply difference of two squares
[tex]\mathbf{x^6 - 16x^2 = x^2(x + 2)(x - 2)(x^2 + 4)}[/tex]
Hence, the equivalent expression of [tex]\mathbf{x^6 - 16x^2}[/tex] is [tex]\mathbf{x^2(x + 2)(x - 2)(x^2 + 4)}[/tex]
