The lateral surface of an object is the area of all the sides of the object, excluding the area of its base and top. For a cube, the lateral surface area would be the area of four sides.For a pyramid, the lateral surface area is the sum of the areas of all of the triangular faces but excluding the area of the base.

Masja [62]

We have

C is the cost

x is the units of a product at the factory

C= 35170

we need to find the value of x

The equation given is

$C=43x+14100$

so we have the value of C, so the equation if we substitute the value of C is

$35170=43x+14100$

we need to isolate the x

$\begin{gathered} 35170-14100=43x \\ 21070=43x \\ x=\frac{21070}{43} \\ x=490 \end{gathered}$

In that month,490 units can be produced for $35170.

If ADAB ACBA, ZDAB = 35° and ZCBA = 8x + 3 A D x = [?] X C B

Answer:

x=4

Step-by-step explanation:

We are given that the triangles are congruent.

Specifically, the order of the letters gives that the angles ∠DAB and ∠CBA are corresponding parts of the two congruent triangles. Since corresponding parts of congruent triangles are themselves congruent, ∠DAB ≅ ∠CBA. Thus, m∠DAB = m∠CBA.

Given the expressions for the two angles, we can substitute into the equation, and solve for the requested variable.

$m\angle DAB=m\angle CBA\\(35)=(8x+3)\\(35)-3=(8x+3\!\!\!\!\!\!\!\!\!\!{--})-3 \!\!\!\!\!\!\!\!\!\! {--}\\32=8x\\\dfrac {32}{8}=\dfrac {8x\!\!\!\!\!\!\! {-}}{8\!\!\!\! {-}}\\4=x$
