Answer:
360mm^2
Step-by-step explanation:
Surface area of a square pyramid= Base area + Lateral area
Base area=10mm × 10mm
=100mm^2
Lateral area = (4) × (1/2) × (10) × √(12) ^ 2 + (5) ^ 2)
= 260 mm^2
Surface area= Base area + Lateral area
=100mm^2 + 260mm^2
= 360mm^2
Answer:
you should get off the team
Step-by-step explanation:
cuz you do not know what to do
The answer is 1,3 you can check
Y-5=3-9(y+2). so so u are going to distribute-9 to y and 2 which is -9y-18
so u are going to add like terms 3 and -18 which is -15. so the next step is going to be y-5=-9y-15 so u are going to add 5 to -5 and -15 to balance the equation and u will get -10 . y=-9y -10. since u are multiplying -9 by y so have to expand it y= -9 * y -10. so u have to divide y by y to get y . -9-10= -19 soo y =-19
