This triangle is isosceles (indicated by the tick marks), which means its base angles are congruent; given this, you can set them equal to each other to solve for x:

3x = 5x - 30
-2x = -30
x = 15

Answer:
x = 15

Hope this helps!

The volume of a rectangular prism is given by the product of its length, and height. Samantha has a rectangular prism that has a
Juli2301 [7.4K]

Answer:

V = a²b³ + acb² units³

Step-by-step explanation:

The volume of a rectangular prism is given by :

V = l×b×h

Here, l = b² units

b = aunits

h = ab+c units

So, the volume of the prism is given by :

V = b² × a × (ab+c)

= ab²(ab+c)

= a²b³ + acb²

Hence, the required volume is a²b³ + acb² units³.

Which correctly describes a cross section of the right rectangular prism if the base is a rectangle measuring 15 inches by 8 inc
grigory [225]
<span>A cross-section parallel to the base is a rectangle measuring 15 inches by 8 inches.

</span><span>A cross-section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 6 inches by 15 inches.
</span>
<span>A cross-section not parallel to the base that passes through opposite 6-inch edges is a rectangle measuring 6 inches by greater than 15 inches.

the cross sections that are parallel and perpendicular will have the same measurements as the non-intersected sides. the last one will be a diagonal so the intersected edge is 6 and it creates a right triangle so it must be larger than 15 inches.
