Hello there,
If c=-2 just plug in -2 for every c you see.
(-2)²-7(-2)-8
This simplifies to
4+14-8
18-8
10
Hope this helps!
Answer:
m∠Q = 121°
m∠R = 58°
m∠S = 123°
m∠T = 58°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Create an expression for the sum of all the angles and equate it to 360, then solve for x:
∠Q + ∠T + ∠S + ∠R = 360
⇒ 2x + 5 + x + 2x + 7 + x = 360
⇒ 6x + 12 = 360
⇒ 6x = 360 - 12 = 348
⇒ x = 348 ÷ 6 = 58
So now we know that x = 58, we can calculate all the angles:
m∠Q = 2x + 5 = (2 x 58) + 5 = 121°
m∠R = x = 58°
m∠S = 2x + 7 = (2 x 58) + 7 = 123°
m∠T = x = 58°
The best and most correct answer among the choices provided by your question is the third choice or letter C.
<span>If ST = 21, SP = 3b – 11, and PT = b + 4, the value of b would be 14.

Answer:
<u>Russell runs 9/50 of a mile or 0.18 miles in one minute.</u>
Step-by-step explanation:
1. Let's review the data given to us for solving the question:
Distance run by Russell = 9/10 of a mile
Time Russell runs 9/10 of a mile = 5 minutes
2. How many miles does he run in one minute?
Speed of Russell = Distance run by Russell / Time Russell runs
Speed of Russell = (9/10) / 5
Speed of Russell = 9/10 * 1/5 = 9/50
Russell runs 9/50 of a mile in one minute. If we want to express the answer in decimals, we have : 9/50 = 0.18
<u>Russell runs 9/50 of a mile or 0.18 miles in one minute</u>
