Solution:
<u>Note that:</u>
- Surface area: 2(LB) + 2(BH) + 2(LH)
<u>Substitute the values given into the expression to find the surface area.</u>
- 2(7 x 10) + 2(6 x 6) + 2(6 x 10)
- => 2(70) + 2(36) + 2(60)
- => 140 + 72 + 120
- => 332 mm²
The surface area of the rectangular prism is 332 mm².
Answer:
2,144.66 in³
Step-by-step explanation:
Thus, the volume of the water in the fishbowl = volume of a sphere having diameter of 16 inches
= 2,144.66 in³
Answer:
I thank it is D
Step-by-step explanation:
The answer is B because it is a positive slope
Answer:
Yes, see the explanation.
Roots:
x = , or x= -10
Step-by-step explanation:
A quadratic fomrual in standard form is;
ax^(2) + bx + c = 0
The given equation:
4x^2 = -9x - 4
Maniplate the equation using inverse operations
4x^2 = -9x - 4
-4x^2 -4x^2
0 = -4x^2 - 9x - 4
Yes, this is a quadratic equation, because it fits the requirement of being able to be written in standard form.
Now find its roots:
-4x^2 -9x - 4 = 0
remember,
x =
Substitute in the given values
x=
Simplify,
x =
x =
x =
or
x= -10
