Answer:
Step-by-step explanation:
To find the area, I divided the shape into squares and rectangles. Then, I found the area of the squares and rectangles and added them,
- Area = (7 x 7) + (18 x 5) + (6 x 4)
- => (49) + (90) + (24)
- => 163 in²
Hence, the area is 163 in.²
Alright so to find the area of a rectangular prism (a book is a rectangular prism) you need to multiply the 3 numbers they give you so you multiply 7, 812, and 2/12. after you multiply all of the numbers you add ^3 to the end because you found the volume, its not a flat shape or a 2D shape.
Answer:
The triangles are not similar
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
<em>Triangle X.Y.Z</em>
---> angle X and angle Y are complementary angles
<em>Triangle H.G.J</em>
---> angle H and angle J are complementary angles
so
X.Y.Z is a
triangle
H.G.J is a
triangle
The measure of its corresponding angles are not congruent
therefore
The triangles are not similar
Generally, you are told to approach these by "clearing fractions". That is, you generally multiply the equations by the least common denominator so all fractions and mixed numbers become integers.
Alternatively, you can simply do the arithmetic using the numbers given. You learned a long time ago how to add, subtract, multiply, and divide mixed numbers and fractions. Do these operations as necessary to solve the equations.
Answer:
= 22 + 3,0 + 1 = 36
= -20 + 3 = -17
= -62 + 10 = -52
= 2 x (-7) = -14
= (-322) - 30 + 11 = 281
