▹ Answer
<em>D. 3x² + 13x - 56</em>
▹ Step-by-Step Explanation
(x + 7)(3x - 8) (<em>Using FOIL method)</em>
x * 3x - 8x + 7 * 3x - 7 * 8
3x² - 8x + 7 * 3x - 7 * 8
3x² - 8x + 21x - 56
3x² + 13x - 56

Answer:
Step-by-step explanation:
if they are Pythagorean triples they should check for the theorem
the biggest value 17/8 should be the hypothenuse
(17/8)² = 1² + (15/8)² ; square the numbers
289/ 64 = 1+ 225/ 64 ; find the common denominator for addition
289/ 64 = 64+ 225/ 64 ; add
289/ 64 = 289 /64 TRUE so they are Pythagorean Triples
Answer:
what is the circle.
Circumference is diameter x 3.14.
Diameter is the whith of a circle.
Ex. diameter = 4
4 x 3.14 = 12.6cm.
Step-by-step explanation:
What we know:
- number of meeting rooms = m
- chairs in each meeting room = 325
Since we need an equation to represent the number of chairs in m meeting rooms, we would multiply the amount of chairs per meeting room (325) by m. This amount is c. So the equation becomes:
c = 325m
Now the question asks for the amount of chairs if there are 7 meeting rooms in the hotel. To find this, substitute 7 for m into c = 325m.
c = 325m
c = 325(7)
c = 2275
Answer:
The equation is c = 325m, and the amount of chairs if m equals 7 is 2,275.
You should calculate like this: 595/5= $119
