Ok, so we know that the radius of Sphere A is 24 cm, and we know that the diameter of Sphere B is 42 cm. To find the radius of Sphere B, all we need to do is divide the diameter by two. The radius of Sphere B is 21 cm. 24 times what factor is 21? Well,
is equal to 21. All we need to do now is simplify it. Divide the numerator and denominator by 3, and we get
rounding to the nearest tenth will be 20
Answer:
8 square units
Step-by-step explanation:
The base is on a horizontal line. The points are 7-3 = 4 units apart.
The side perpendicular to the base is a vertical segment 6 -2 = 4 units long.
The area is ...
A = 1/2bh
A = 1/2(4 units)(4 units) = 8 units²
The area of the triangle is 8 square units.
__
It is effectively half of a square that is 4 units on a side. 1/2(4²) = 8.
Answer:
B. (x+2) is a factor
Step-by-step explanation:
3x^2 -x-14
3x^2+6x-7x-14
3x(x+2)-7(x+2)
(3x-7)(x+2)
so, x+2 is a factor of 3x^2-x-14
