Answer:
Step-by-step explanation: i think this is unsolvable because you need two angle measurements to figure out the third angle...
Answer:
(8, - 5 )
Step-by-step explanation:
Given the 2 equations
3x + 4y = 4 → (1)
- x - 3y = 7 → (2)
Multiplying (2) by 3 and adding to (1) will eliminate the x- term.
- 3x - 9y = 21 → (3)
Add (1) and (3) term by term to eliminate x, that is
0 - 5y = 25
- 5y = 25 ( divide both sides by - 5 )
y = - 5
Substitute y = - 5 into either of the 2 equations and solve for x
Substituting into (1)
3x + 4(- 5) = 4
3x - 20 = 4 ( add 20 to both sides )
3x = 24 ( divide both sides by 3 )
x = 8
solution is (8, - 5 )
Answer:
If you're supposed to be multiplying the first four numbers, the answer is going to be 13.
Step-by-step explanation:
B can be eliminated, as 10x and 4x multiply to 40x^2, which is not in the expression.
The greatest common factor of all coefficients in the equation is 2. Divide all coefficients by 2 to get the following equation:

We will leave out this coefficient, 2, for now.
We'll need to find the factors of c:
c = -6
Factors of 6: {1,2,3,6}
The only factors in the answer choices that fit this are 2 and 3. D can be eliminated.
5x and 2x multiply to 10x^2. 5x and 2x also modify what b will equal. Use the answer choices A and C to find b:
A.

C.

Answer C comes up with the correct b value.
The answer is
C. 2(5x - 2)(2x + 3).
