7y. the 7x cancels out and if u distribute, it's 7y.
Answer:
x = 25
Step-by-step explanation:
The volume (V) of the triangular prism is calculated as
V = Al ( A is the area of the triangular face and l is its length )
A = bh = 0.5 × 5 × 8 = 20 cm² , then
V = 20 × 20 = 400 cm³
The volume of the cuboid is calculated as
V = lbh = 3.2 × 5 × x = 16x
Given V = 400 cm³ , then
16x = 400 ( divide both sides by 16 )
x = 25
-4,2,-1
Just multiply each term by (-1/2)
The value of x according to the information given about the trapezoid is; 5.375
<h3>Isosceles trapezoid</h3>
The sum of angles in a trapezoid like other Quadrilaterals is; 180°.
However, since the trapezoid is Isosceles, Top angles are equal and bottom angles are equal too.
Hence, we have;
