Answer:
The surface area of the given pyramid is 112 
.
Step-by-step explanation:
Base length of the pyramid = 4 inches
Area of the base = 
= 
= 16
Area of its base = 16
Area of one of its triangular surface = 
x base x height
= x 4 x 12
= 2 x 12
= 24
Area of all its four triangular surfaces = 4 x 24
= 96
surface area of the pyramid = sum of areas of all its surfaces
= 16 + 96
= 112
The surface area of the given pyramid is 112 .

Answer:
(-6) - 7 and -6 - (-4)
Step-by-step explanation:
you have to find the rate of change.
this equals -13/4=3.25
The options Patel has to solve the quadratic equation 8x² + 16x + 3 = 0 is x = –1 Plus or minus StartRoot StartFraction 5 Over 8 EndFraction EndRoot.
<h3>Quadratic equation</h3>
8x² + 16x + 3 = 0
8x² + 16x = -3
8(x² + 2x) = -3
- Using completing the square
8(x² + 2x + 1) = -3 + 8
8(x² + 1) = 5
(x² + 1) = 5/8
- Taking the square root of both sides
(x + 1) = ± √5/8
x = -1 ± √5/8
Therefore,
x = –1 Plus or minus StartRoot StartFraction 5 Over 8 EndFraction EndRoot

Answer:
5 + 3p ≥ 30
Step-by-step explanation:
"at least" means greater than are equal to. ≥
So we already know he has 5 points, but the other 3 rounds we don't. 5 + 3p
30 is the overall points he has.
5 + 3p ≥ 30
