Answer:
If it's a rectangle, then:
12 x 6 = 72 cm²
Step-by-step explanation:
Answer:
uhh either 4/4 1 or 2/2
Step-by-step explanation:
if the words covered by the light reflection says "the shaded part", then there are 4 total pieces, which means all four are shaded.
Answer:
y = -3x - 12
Step-by-step explanation:
Lines that are parallel have the same gradient.
Therefore using the point (-2,-6) you can make your own equation.
-6 will be y, -2 will be x
All you have to do is find the y-intercept which is C in <em>y</em><em>=</em><em>mx</em><em>+</em><em>c</em>
-6 = -3(-2) + c
-6 = 6 + c
-12 = c
Therefore;
<u>y = -3x - 12</u>
Answer:
81x + 4913x + 676x + 10x + 12 / 9
X=5692 /9
X=632.444
Okay. The equation for a sphere's surface area is A = 4 * pi * r^2. Let's plug 5 in for r.

I got 314 cm^2 is the surface area, but it always helps to double check work! Hope this helps!
