Answer:

C. 120

Step-by-step explanation:

area of trapezoid = (base1 + base2)h/2

area = (10 cm + 6 cm) * 15 cm/2

area = 16 cm * 15 cm / 2

area = (240 cm^2)/2

area = 120 cm^2

Which steps will generate an expression equivalent to 17(+5)
Bingel [31]

For this case we must indicate an expression equivalent to:

17 (x + 5)

By definition we have that the distributive property establishes that:

a (b + c) = ab + ac

Then, applying the property to the given expression we have:

17 (x + 5) = 17 * x + 17 * 5 = 17x + 85

Thus, an equivalent expression is:

17x + 85

ANswer:

17x + 85

Slope = -1/6; (12,-2)
stira [4]

Equation is y = -1/6x

Step-by-step explanation:

  • Step 1: Given that slope, m = -1/6 and a coordinate (12,-2). Write the equation and find the y-intercept, b.

⇒ y = mx + b

⇒ -2 = -1/6 × 12 + b

⇒ -2 = -2 + b

∴ b = 0

  • Step 2: Write the equation in slope intercept form.

⇒ y = -1/6x + 0

⇒ y = -1/6x

Consider a circle that has a circumference of 28/3.14 centimeters. What is the area of this circle? Answer fast plz also can you
bija089 [108]

Answer:

A=6.33\ cm^2

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The circumference of a circle is equal to

C=2\pi r

we have

C=\frac{28}{3.14}\ cm

\pi=3.14

substitute the values

\frac{28}{3.14}=2(3.14)r

r=\frac{28}{19.7192}\ cm

r=1.42\ cm

step 2

Find the area of the circle

The area of the circle is equal to

A=\pi r^{2}

substitute the values

A=(3.14)(1.42)^{2}

A=6.33\ cm^2
