Combine like terms:
<span>3y + 5z + 8y - 3z = (3y + 8y) + (5z - 3z) = 11y + 2z

So you would choose A confidently

What is the perimeter of the triangle?
Dennis_Churaev [7]
Answer:

The perimeter will be 30

Step-by-step explanation:

Perimeter = all side lengths added

Step 1. Determine the length of the triangle

Answer: 5

Step 2. Determine the width of the triangle

Answer: 12

Step 3. Determine the diagonal line across the triangle

Answer + explanation:

For it to figure it out, we must use this method called Pythagorean Theorem

Pythagorean Theorem: a^2 + b^2 = c^2

Where a = 12 b = 5 and c = the diagonal line

12^2 + 5^2 = c^2

144 + 25 = c^2

c^2 = 169

c = 13

The diagonal line measures 13 units

Step 4. Add all of the dimensions we just reviewed

Answer:

Length = 5

Width = 12

Diagonal line = 13

5 + 12 + 13 = perimeter

perimeter = 30

Therefore, the perimeter is 30

Angles 1 and 2 are complementary and congruent. what is the measure of angle 1? 30° 45° 50° 75°
lesantik [10]

see the attached figure to better understand the problem

we know that

1) If angle 1 and angle 2 are complementary angles

then

m∠1+m∠2=90\° ------> equation A

2) If angle 1 and angle 2 are congruent angles

then

m∠1=m∠2 ------> equation B

Substitute equation B in equation A

m∠1+(m∠1)=90\°

2m∠1=90\°

m∠1=45\°

therefore

<u>the answer is</u>

45\°

IrinaK [193]

Answer:

The number of confirmed cases is the independent variable.

The number of deaths is the dependent variable.

Why?

<u>The number of deaths is dependent on the fact that there are cases, so the number of deaths is a dependent variable.</u>

A triangle should always add up to 180 degrees. So just add up the angles you have and subtract them from 180
