Answer:
steps below
Step-by-step explanation:
1+2+3+4+896+897+898+899
= (1+899)+(2+898)+(3+897)+(4+896)
= 900 + 900 + 900 + 900
= 3600
Answer:
8 cm
Step-by-step explanation:
(See the image attached for details)
- The blue segment measures 15 cm
- The green segment measures 7 cm
- The green and yellow segment when added form the blue segment
- So: ? + 7 = 15
Solve:
? + 7 = 15
Subtract 7 on both sides:
? + 7 = 15
-7 -7
? = 8 cm
Therefore, the yellow segment, or the missing side length, measures 8 cm.
Answer:
s=P-b/2
Step-by-step explanation:
P-b=2s
P-b/2=s
Answer:
(-2, -1).
Step-by-step explanation:
y = x² + 4x + 3
Completing the square:
y = (x + 4/2)^2 - (4/2)^2 + 3
y = (x + 2)^2 - 4 + 3
y = (x + 2)^2 - 1.
This is vertex form and the coordinates of the vertex are (-2, -1).
Hope this helps. (p.s. there is 7 zeros in 91,250,000,000)
