Answer: b

Step-by-step explanation:

You know the formula of a triangle is: (base*height)/2

So: 4*8=32

32/2=16cm^2

Since its a parallelogram, you could say that there are two of these triangles, so: 16*2=32cm^2

Now we're left with the part in the middle. The sides are now 8 by 8 because we took away 4 from 12, so: 8*8= 64cm^2

Now you just add all your values together, so: 32+64=96cm^2

Answer:

314 m²

Step-by-step explanation:

the surface area of a sphere (As) is

As = 4×pi×r²

our radius r (half of the diameter) here is 5m.

As = 4×3.14×5² = 4×3.14×25 = 100×3.14 = 314 m²

Describe a pattern shown in this sequence, and use the pattern to find the next two terms.

kotegsom [21]

The pattern is adding 8 to the previous number.
ex. 7+8=15, 15+8=23, 23+8=31, 31+8=39
Now for the next 2 terms:
39+8=47
47+8=55
Hope this helps!

Answer:

The equation of line in the form of Ax + By = C is: $\mathbf{4x+y=-17}$

Step-by-step explanation:

We need to find the equation of line, with the given slope passes through the given point.

Slope m = -4

Point: (-2,-9)

We need to find slope and y-intercept of the line.

The slope of line is given m = -4

Now, we need to find the y-intercept

Using the point (-2,-9) and slope m = -4, we can find y-intercept

The formula used will be: $y=mx-b$

Putting values of: y= -9, x =-2 and m = -4

$y=mx+b\\-9=-4(-2)+b\\-9=8+b\\b=-9-8\\b=-17$

So, y-intercept b = -17

Now, the equation of required line having slope m = -4 and y-intercept b = -17 is:

$y=mx+b\\y=-4x-17$

Writing equation in required form i.e. of Ax + By = C

$y=-4x-17\\4x+y=-17$

So, the equation of line in the form of Ax + By = C is: $\mathbf{4x+y=-17}$
