We know that
[surface area for a rectangular prism with a square base ]=2*s²+4*s*h
2*s²----> Is the surface area of the bases
4*s*h---> is the lateral area
s=2 units
h=4 units
[surface area for a rectangular prism with a square base ]=2*2²+4*2*4
surface area=8+32----> 40 units²
the answer is
40 units²
Answer:
90% Increase
Step-by-step explanation:
80+72=152
72/80= .9
Answer:
Step-by-step explanation: First you would do this 1260.90 divided by 6 = 210. So then you would multiply 210 x 2 = 420. $420 is how much the people who are staying for 6 days. Then since we know it’s $210 per day, we would subtract $420 from 1260.90 and we would get 840.90. Divide that by 6 and get 140. 140 is how much those two people are paying for 2 nights.
X + 7 < 2x +7
therefore
<span>x < 2x
</span>x > 0
another:
25 + 7 > 10 + 7
therefore
25 > 10
4x - 3y - 7 = 0
-3y = -4x + 7
y = 4/3x - 7/3....slope here is 4/3
A. a parallel line will have the same slope
y = mx + b
slope(m) = 4/3
(-2,1)...x = -2 and y = 1
sub and find b, the y int
1 = 4/3(-2) + b
1 = -8/3 + b
1 + 8/3 = b
3/3 + 8/3 = b
11/3 = b
so ur parallel line is : y = 4/3x + 11/3
B. A perpendicular line will have a negative reciprocal slope. To get the negative reciprocal of a number, u flip the number and change the sign. So our perpendicular line will need a slope of -3/4
y = mx + b
slope(m) = -3/4
(-2,1)...x = -2 and y = 1
sub and find b, the y int
1 = -3/4(-2) + b
1 = 3/2 + b
1 - 3/2 = b
2/2 - 3/2 = b
-1/2 = b
so ur perpendicular equation is : y = -3/4x - 1/2
