<span>A cube has 6 square faces, so each face would have area 200 sq in/6=33.33 sq in
Since the area of each face equals the square of the sides, the edge of the cube would be = approx. 5.77 in</span>
Answer:
58.6*14=820.4 miles
Step-by-step explanation:
Answer:
The answer is the D : 729
Step-by-step explanation:
The area of a cube is wide x length x height
9x9x9 = 729
Answer:
Q1 m² +10m+ 21
Q2
a) 3 (2 +3x)
b) (y+4) (y-4)
c) (2p-5) (p+2)
Step-by-step explanation:
Q1. expand and simplify (m+7)(m+3)
solution
(m+7)(m+3)
m² + 7m+ 3m + 21
m² +10m+ 21
Q2 Factorize
a) 6 +9x
Answer
Taking 3 common
3 (2 +3x)
b) y² -16
answer
y² -4 as formula a² –b² = (a+b)(a-b)
(y+4) (y-4)
c) 2p² –p-10
So according to quadratic equation
a=2 b=-1 c=-10 a x c =-20 b=-1
we need two number whose product is -20 and sum is -1
-5 x 4 = -20 -5 +4 = -1
2p² –p-10 = 2p² + 4p-5p-10
=2p (p +2) -5 (p+2)
= (2p-5) (p+2)
please mark me brainliest :D
