9. If mA 48", then mB= ? and mC = ?.
10. If mB 83, then mA = ? and mC = 2.
11. If mC 127, then m28= ? and mA = ?.
12. If mA = 25. than mB= ? and mC = ?.
9. if mA = 48° , then
mB = 90° - 48° = 42°mC = 180° - 42° = 138°10. if mB = 83°, then
mA = 90° - 83° = 7°mC = 180° - 83° = 97°11. if mC = 127°, then
mB = 180° - 127° = 53°mA = 90° - 53° = 37°12. if mA = 25°, then

Please help me out!!!!
Answer:
All real numbers
Step-by-step explanation:
4(x+1) = 4x+4
Distribute
4x+4 = 4x+4
Subtract 4x from each side
4x+4-4x = 4x+4-4x
4=4
This is always true so there are infinite solutions
Solution:
Let's find the required solution,
→ 4(x + 1) = 4x + 4
→ 4x + 4 = 4x + 4
→ (4x - 4x) + 4 = 4
→ 4 = 4
→ LHS = RHS
The answer is all real numbers.

Find the discriminate, number of roots and solve the quadratic equation using the quadratic formula -my answers are pribably wrong
Answers:
discriminant = dnumber of roots = esolutions = g=================================================
Explanation:
Let's compute the discriminant. Here we have a = 1, b = 1, c = -2
d = b^2 - 4ac
d = 1^2 - 4(1)(-2)
d = 9
The fact that d > 0 tells us we have two different real number solutions.
------------------------
We can use the quadratic formula to solve, or we can factor. I'll use the factor method.
x^2 + x - 2 = 0
(x - 1)(x + 2) = 0
x-1 = 0 or x+2 = 0
x = 1 or x = -2
The two solutions are -2 and 1

ITS SECOND QUESTION WITH DIAGRAM
If z^1/2 = x^1/2 + y^1/2 , prove that (x + y - z)^2 = 4xy.
HELPP MEEEEE
Answer:
Make use of the fact that [tex](a + b)^{2} = a^{2} + 2\, a\, b + b^{2}[/tex].
Step-by-step explanation:
Start from the given: [tex]z^{1/2} = x^{1/2} + y^{1/2}[/tex].
In other words: [tex]\sqrt{z} = \sqrt{x} + \sqrt{y}[/tex].
Square both sides of the equation:
[tex](\sqrt{z})^{2} = (\sqrt{x} + \sqrt{y})^{2}[/tex].
Equality would still hold because:
[tex]\begin{aligned}& a = b \\ \implies \; & a\cdot a = a\cdot b \\ \implies \; & a \cdot a = b \cdot b \\ \implies \; & a^{2} = b^{2}\end{aligned}[/tex].
Simplify:
[tex]z = (\sqrt{x})^{2} + 2\, (\sqrt{x}) \cdot (\sqrt{y}) + (\sqrt{y})^{2}[/tex].
[tex]z = x + 2\sqrt{x y} + y[/tex].
Subtract [tex]z[/tex] from both sides of this equation:
[tex]0 = x + 2 \sqrt{x y} + y - z[/tex].
Subtract [tex]2 \sqrt{x y}[/tex] from both sides of this equation:
[tex]-2 \sqrt{x y} = x + y - z[/tex].
Again, square both sides of this equation:
[tex](-2 \sqrt{x y})^{2} = (x + y - z)^{2}[/tex].
[tex](-2)^{2}\, (\sqrt{x y})^{2} = (x + y - z)^{2}[/tex].
[tex](x + y - z)^{2} = 4\, x \, y[/tex] (by the symmetric property of equalities.)

Benny spent half of his allowance going to the movies. He washed the family
car and earned 8 dollars. What is his weekly allowance if he ended with
13 dollars ?
Let it be x
He spent x/2 dollars then

Find the Quotient and Remainder. 5x^3 - 6x^2 + x + 7 divided by x^2
Step-by-step explanation:
Solution
According to remainder theorem, when f(x) is divided by (x+2), Remainder =f(−2)
f(x)=5x3+2x2−6x+12
f(−2)=5(−2)3+2(−2)2−6(−2)+12
=5×−8+2×4+12+12
=−40+32=−8
∴ Remainder=−8

The movie ended at 7:05 p.m. and lasted 2 hours 40 minutes. What time did the movie begin?
Answer:
4 : 25pm
Step-by-step explanation:
If the movie ended at 7:05p.m, and the movie is as long as 2 hours 40 minutes, therefore the starting time is 2 hours 40 minutes earlier than the ending time
Therefore
7:05 - 2 hours and 40 minutes
= 4 : 25pm

Answer:
48
Step-by-step explanation:
u • w
= (i + 6j ) • (9i - 2j )
= (1 × 9 ) + (6 × - 2 )
= 9 + (- 12)
= 9 - 12
= - 3
v • w
= (5i - 3j ) • (9i - 2j )
= (5 × 9) + (- 3 × - 2)
= 45 + 6
= 51
Then
u • w + v • w
= - 3 + 51
= 48
Solve 2x + 4 = 12.
O A. x = -4 and x = -8
O B. x = -4 and x = 8
O C. x = 4 and x = -8
O D. x = 4 and x = -4
If ; | 2x+4|=12 —> x = 4 , x = – 8 —> The choose C.
If ; | 2x | +4=12 —> x =4 , x = – 4 —> The choose D.
