Answer:

Step-by-step explanation:

Since it is only addition and subtraction, you can rearrange the order of the equations. This is what the three eqautions will look like after the arrangement:

1.6z + 8.3 z = ? (9.9z)

6.2y - 5.1y = ? (1.1y)

4.3x + 5.5x = ? (9.8x)

Then you just add and subtract.

Answer:

m < EAD = 29 degrees

m < CAB = 119 degrees

Given :

The question states that m < CAE = m<FAB = 61 degrees and m<DAF = 90 degrees

Solution:

1. Since line CAF and EAB intersect each other, m<CAF = m< EAF - (opposite vertical angles are equivalent)

2. m<BAC + m<EAC = 180 degrees (sum of linear pair)

3. m<CAB = 180 degrees - m<EAC

4. Equation 1: m<CAB = m<EAF = 119 degrees

5. m<EAF = m<EAD + m< DAF

6. m<EAD = m<EAF - m<DAF

7. m<EAD = 119 degrees-90 degrees = 29 degrees

Hope this helps!!! :)

Which of the following is the correct factorization of the polynomial below?

Finger [1]

Step-by-step explanation:

(x+3)(x-5)

= x²-5x+3x-15 = x²-2x-15

But the given polynomial x³-15

So it is not the correct factorization.

Again, (x-3)(x+5)

= x²+2x-15

But the given polynomial x³-15

So it is not the correct factorization.

Again , (x+3)(x²-4x+5)

= x³-4x²+5x+3x²-12x+15

= x³-x²-7x+15

But the given polynomial x³-15

So it is not the correct factorization.

So , optionD is the correct answer
