Answer:
move 50x on to the other side then move 500 to the other side too so that it reads 25x-50x *sign*250-500
Step-by-step explanation:
-25x*sign*-250 divide both sides by 25so answer x*sign*100
Answer:
The quotient of 7 and 14 is 2..
Answer:
4 inches
Step-by-step explanation:
The surface area, A of a right square pyramid is given by :
A = a² + 2as
Where, s = height of each triangular surface = x
a = base edge of pyramid
Substituting values into the equation :
A = 84 in² ; a = 6 in ; Slant height, s = x
84 = 6² + 2(6 * x)
84 = 36 + 2(6x)
84 = 36 + 12x
84 - 36 = 12x
48 = 12x
48/12 = 12x / 12
4 = x
Hence, Slant height, x = 4 inches
Hey there! :)
Answer:
16 m².
Step-by-step explanation:
Find the surface area by finding the areas of each face:
The base is a square, so use the formula A = s²
A = 2²
A = 4 m².
Find the areas of the congruent triangular lateral sides. Use the formula:
A = 1/2 (bh)
A = 1/2 (2 · 3)
A = 1/2 (6)
A = 3 m².
There are 4 triangular faces, therefore:
3 × 4 = 12 m².
Add up the areas from the triangles and square base:
12 + 4 = 16 m².
Therefore, the surface area of this square pyramid is 16 m².
