Answer: 9+-1=8
Step-by-step explanation: With the - sign, the + sign cancels out because, a(9) is positive(+). Unless a(9) were to be negative (for example: -25 + -1 = -26), you subtract from the positives.

In the expression 4x+ 2y -3x +5y^2 +3z- 4z^2
O 2y and 5y2
0 4x and -3x
0 -3x and 32
3z and 4z^2
Answer:
4x and -3xStep-by-step explanation:
We can simplify only like terms in an algebraic expression.
Terms are "like terms" only if they consist the same letters with the same exponent.
The only difference between like terms is their coefficients are different.
So:
2y and 2y² are not like terms (different exponents at y)
4x and -3x are like terms (the same letter, the same exponent)
-3x and 32 aren't like terms (no x with 32 means different exponents)
or if you meant:
-3x and 3z aren't like terms (different letters)
3z and 4z² aren't like terms (different exponents at z)
The map below shows the length of a proposed land bridge at Phil Hardberger Park. The length of the land bridge is represented by PH
in the map below.
P(2,55)
H(32, 15)
On the map, each unit represents 1 yard. To the nearest yard, what is the actual length of the land bridge from P to H?
A 50 yards
B. 150 yards
C. 78 yards
D. 234 yards
Answer:
A; the actual length of the land bridge from P to H is 50 yards
Step-by-step explanation:
Here in this case, given the coordinates of P and H, we want to calculate the actual length of the distance between the two points.
Mathematically, to calculate this distance, we make use of the distance formula;
D = √(x2-x1)^2 + (y2-y1)^2
In this case, (x1,y1) = (2,55) while (x2,y2) = (32,15)
Substituting these values
D = √(32-2)^2 + (15-55)^2
D = √(-30)^2 + (-40)^2
D = √(900 + 1600)
D = √(2,500)
D = 50 units
Now, we know that each units represent 1 yard, thus 50 units will represent 50 * 1 = 50 yards

AC = 120. What
are AB and BC?
Answer:
AB = 42
BC = 78
Step-by-step explanation:
AB = 4x + 6
BC = 7x + 15
AC = 120
A to B plus B to C is the same distance as from A to C, which is 120.
AB + BC = AC
(4x + 6) + (7x + 15) = 120
4x + 7x + 6 + 15 = 120
11x + 21 = 120
Subtract 21 from both sides.
11x = 120 - 21 = 99
11x = 99
Divide both sides by 11.
x = 9
AB = 4x + 6 = 4*9 + 6 = 36 + 6 = 42
BC = 7x + 15 = 7*9 + 15 = 63 + 15 = 78
Answer:
AB = 42
BC = 78
Answer:
x = 9
AB = 42
BC = 78
Step-by-step explanation:
AB + BC = AC
4x + 6 + 7x + 15 = 120
11x + 21 = 120
11x = 99
x = 9
AB = 4x + 6 = 4(9) + 6 = 36 + 6 = 42
BC = 7x + 15 = 7(9) + 15 = 63 + 15 = 78
