5 more than the sum of -1 and -12
lets start with the 2nd part, the sum of -1 and -12
sum means adding 2 things together, so -1 + -12 = <u>-13</u>
now lets work on the first part again, it said 5 MORE, more means add as well, so
-13 + 5 = -8
3x+5 = a
a * 6x = 18x^2 + 30x
R = 15x + 29
a * 5 = 15x + 25
R = 4
answer: 6x + 5; R = 4
Answer:
-infinity < y ≤ 2
Step-by-step explanation:
A is correct. The largest value y can have is 2, whereas there is no smallest value. -infinity < y ≤ 2
Answer:
125 meters squared
Step-by-step explanation:
Surface area of initial pyramid:
- A= 10²+4*1/2*10*15= 400 m²
Surface area of extended pyramid:
- A= 10*15+2*1/2*15*15+2*1/2*10*15= 525 m²
The difference is:
