Answer:

x=8

x=-6

Step-by-step explanation:

As We Have -x^2+2x +48=0

By Using Ist And Last Method (factorization Method)

=> -x^2+8x-6x+48=0

Taking x and +6 common

=>x(-x+8)+6(-x+8)=0

Taking -x+8 common

=> -x+8=0 and x+6=0

=>-x+8=0 =>-x+8-8=0-8 (subtracting 8 on both side) => x=8

and

x+6=0 =>x+6-6=0-6 (subtracting 6 on both side) => x=-6

Solve for θ. sin(74) = cos(θ) 1. 6° 2. 74° 3. 36° 4. 16°

Marianna [84]

Sin74 = Cos16

cause 16 + 74 = 90

Whenever the sum of two angles is equal with 90, the Sin of one is equal with the Cos of the other like :

Sin(30) = Cos(60)

and also

Tan(30) = Cot(60)

8(7 + 23) = 8(7) + 8(?)

34kurt

Answer: 23

When using multiplication with brackets, you multiply the number by all the numbers within the bracket before adding them together.

Therefore when it is 8(7 + 23) it basically means: 8(7) + 8(23)

Christian wants to make an A in his class. There are 5 exams this year, and he has taken 4 of them. His grades were 84, 88, 95,

ioda

Answer:

last test grade=x x ≥ 79 so 79%

Step-by-step explanation:

(84/5)+(88/5)+(95/5)+(104/5)+(x/5) ≥ 90

Simplify: (371/5)+(x/5) ≥ 90

Subtract (371/5) from both sides

Then you have (x/5) ≥ (79/5)

Then multiply both sides by 5 and you have x ≥ 79
