Answer:
i think its 63,64,65. Tell me if I am wrong
Step-by-step explanation:
Answer: 48
Step-by-step explanation:
2x - 1 = 6
Add 1 to both sides of the equation , we have:
2x = 7
divide through by 2
x = 7/2
The value of - 1 will be calculated by substituting in the value of x , that is
- 1 = 4( - 1
= 4() - 1
= 49 - 1
= 48
Answer:
48
Step-by-step explanation:
2x-1=6
2x=6+1
2x=7
x=7/2
------------
4x^2-1
4(7/2)^2-1
4(49/4)-1
49-1
48
Write an expression that represents the perimeter, in centimeters, of the triangle.
Show all work.
PART B:
Write an equivalent expression to represent the perimeter from PART A. by factoring out the greatest common factor.
Show all work.
IF ANSWER BOTH I WILL GIVE BRAINIEST
Answer:
Step-by-step explanation:
Part A : Since sides of triangle are ( 1.9x + 6.2y )cm
(2.5x + 8.3w)cm and (1.6w - 5.1y)cm.
Now perimeter of a triangle = sum of all sides length
Perimeter = (1.9x + 6.2y) + (2.5x + 8.3w) + (1.6w - 5.1y)
= (1.9x + 2.5x) + (6.2y - 5.1y) + (8.3w + 1.6w)
[ collecting the like terms together ]
Perimeter = 4.4x + 1.1y + 9.9w
Part B : Now we factorize the term for perimeter given in part A.
Perimeter = 1.1 (4x + y + 9w)
So equivalent factor will be (1.1 (4x + y + 9w).
Answer:
see explanation
Step-by-step explanation:
A
The perimeter is the sum of the 3 sides, thus summing the 3 sides
1.9x + 6.2y + 2.5x + 8.3w + 1.6w - 5.1y ← combine like terms
= 4.4x + 1.1y + 9.9w ← expression for perimeter
B
Factor out 1.1 from each term, thus
4.4x + 1.1y + 9.9w
= 1.1(4x + y + 9w) ← perimeter in factored form
Answer:
The speed of the jet is
Step-by-step explanation:
The speed traveled by the jet can be found using the relationship between distance and time. Because the problem gives the values for distance and time, they must be replaced in the equation and in this way the requested speed will be found.
1. Write the general equation for the speed:
2. Replace the values of distance and time on the general equation for the speed and make the mathematical operations:
Therefore the speed of the jet is
Answer:
9 M
Step-by-step explanation:
a^2+b^2=c^2
12^2+b^2=15^2
144+b^2=225
-144 -144
b^2=81
b=sqrt of 81
b=9
