Answer:
5100 mm², hope that helps! (OwO)
Step-by-step explanation:
surface area]=2*[area of the base]+[perimeter of the base]*height
area of the base=30*70-----> 2100 mm²
perimeter of the base=2*(30+70)-----> 200 mm
height=4 1/2 mm-----> (4*2+1)/2-----> 9/2 mm
[surface area]=2*[2100]+[200]*9/2-----> 5100 mm²
Answer:
B
Step-by-step explanation:
(8x + 8)(x + 3) = 
= 
.
A: no solution!
first, simplify each side of the equation.
3x + 5 - 10x simplifies to -7x + 5.
8 - 7x - 12 simplifies to -7x - 4.
then, add +7x on both sides of the equation to get the variable alone. if you add 7x to each side, you get left with 0.
so, that leaves 5 = -4 which is not true. so, that means there is no solution.
