The final result is:
no solutionSince we canceled 8x out on each side of the problem, we got 16 = -6 which is false.
Answer:
D. 296 square inches
Step-by-step explanation:
The surface area of a prism is the total area of all its faces.
A triangular prism has three rectangular faces and two triangular faces.
As all 3 sides of the triangle face of this prism are equal, each of the 3 rectangular faces are also equal in area.
<u>Formulae</u>
- Area of a triangle = 1/2 x base x height
- Area of a rectangle = width x length
From inspection of the diagram:
⇒ Area of a triangle = 1/2 x 8 x 7 = 28 in²
⇒ Area of a rectangle = 8 x 10 = 80 in²
<u>Total surface area</u>
Total surface area = 3 rectangle areas + 2 triangle areas
= (3 x 80) + (2 x 28)
= 296 in²
The inverse of the equation would be solving for x, so the answer is..
the square root of y-2 with 3 as the index, and the whole equation divided by 7 the equaled to x.
Answer:
∠ABD ≅ ∠DBC - Given.
∠ABD and ∠DBC are complimentary angles - Given.
∠ABD + ∠DBC = 90° - Definition of complimentary angles.
∠ABD + ∠DBC = ∠ABC - Angle addition postulate.
∠ABC = 90° - Substitution property.
∠ABC is a right angle - Definition of a right angle.
