Answer:
15
Step-by-step explanation:
take the triangle away from the square you will get 9 for the square 3x3 you get the 3 from 7 because 7-3=4 the 4 if for the triangle 4x3=12 divided by 2 bc its a triangle u get 6 6+9=15
Its R
you can just see in figure as square root of 50 is approximately around 7.07
Answer:
A is the answer.
Step-by-step explanation:
What you do is you multiply -6 into each of the fractions and then add or minus the fractions together.
-6(1/4x)=-3/2x
-6(-2/3x)=4x
-6(5/6x)=-5x
-3/4x+4x-5x=-2.5 or A.
the quickest way to do this would be to multiply 1,375 by 3 and then add 2.
1,375 * 3 = 4,125 + 2 = 4,127
correct!
Answer:

Step-by-step explanation:
<u>Surface Areas
</u>
Is the sum of all the lateral areas of a given solid. We need to compute the total surface area of the given prism. It has 5 sides, two of them are equal (top and bottom areas) and the rest are rectangles.
Computing the top and bottom areas. They form a right triangle whose legs are 4.5 mm and 6 mm. The area of both triangles is

The front area is a rectangle of dimensions 7.7 mm and 9 mm, thus

The back left area is another rectangle of 4.5 mm by 9 mm

Finally, the back right area is a rectangle of 6 mm by 9 mm

Thus, the total surface area of the prism is
