(a+b)(a-b)=a^2 - b^2
so
<span>(4x-7)(4x+7) = 16x^2 - 49
answer
</span>16x^2 - 49
Answer:
4x+50y+11
hope this helps :) plz brainliest
Step-by-step explanation:
Answer:
(-1, 3)
Step-by-step explanation:
5x + 2y = 1
+
2x - 2y = -8
7x = -7
x= -1
2(-1) - 2y = -8
-2 - 2y = -8
-2y = -6
y = 3
There you go!! Let me know if you have questions
Assuming that 2000:1 is a ratio of unknown units to centimeters, we can use proportions to find the actual length of the organism.
x = 2000(5.6)
x = 11200
The actual length of the organism is 11,200 units.
