Answer:</h2>
<u>The surface area is </u><u>104 cm²</u>
<h2>
Step-by-step explanation:</h2>
The surface area of rectangular prism is given by
A=2 (wl + hl + hw)
by putting the values we get
A =2 ( 2x6 + 5x6 + 5x2)
A = 104
Answer:
c. y = -x +2
Step-by-step explanation:
pass (0,2): y interception = 2
Line: y=mx+b b=2
x = -5 + 5√3
Step-by-step explanation:
A = ℓ × w
50 = (x + 10) × x
50 = x² + 10x
x² + 10x - 50 = 0
x = [-b ± √(b² - 4ac)] / 2a
x = [-10 ± √(10² - 4(1)(-50))] / 2(1)
x = [-10 ± √(100 - (-200))]/2
x = [-10 ± √300]/2
x = [-10 ± 10√3]/2
x = [-5 ± 5√3]
because x is a unit of length, it is positive
x = -5 + 5√3
:) Well, I dunno about anyone else but this question makes my head spin!
Answer:
y=-2 x=-2
Step-by-step explanation:
y=-x-4
y=x
you can plug y in for x in the first equation by using substitution
y=-y-4
and then you solve for y
2y=-4
y=-2
so y equals -2. Since y=x, x also equals -2. Therefore
y=-2 x=-2
