Step-by-step explanation:
1. 6(9+3)=57
2. 3(12+6)+2(4)=29
3. 5(3-16)=65
(3×4+12(4)=48
Answer:
A midsegment (or midline)
Step-by-step explanation:
In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints.
Answer:
-51
Step-by-step explanation:
56 - 90= -34
times two = -68
minus -17 =-51
Answer:
81
Step-by-step explanation:
Substitute 3 in place of y
7 * 3 * 3 - 16 + 5 * 3 *2 + (16 / 4)
63 - 16 + 30 + 4
Answer:
<h3>r = -13</h3>
Step-by-step explanation:
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
We have the slope m = 2/3 and the points (-4, 3) and (r, -3). Substitute:
![\dfrac{-3-3}{r-(-4)}=\dfrac{2}{3}](https://tex.z-dn.net/?f=%5Cdfrac%7B-3-3%7D%7Br-%28-4%29%7D%3D%5Cdfrac%7B2%7D%7B3%7D)
<em>cross multiply</em>
<em>divdide both sides by 2</em>
![r+4=(-3)(3)](https://tex.z-dn.net/?f=r%2B4%3D%28-3%29%283%29)
<em>subtract 4 from both sides</em>
![\boxed{r=-13}](https://tex.z-dn.net/?f=%5Cboxed%7Br%3D-13%7D)
