Answer:

Step-by-step explanation:

We know that all angles are equal to 180.

The angle right next to the letter see is a Right Angle that equals 90 degrees.

To find the sum of angle A, we have to do some simple math.

180-90= 90

Then we have two angles left. We have to divide 90 in half.

90/2= 45

then to check your work: 90+45+45= 180

So angle A is 45 degrees.

Laila made 12 muffins. Shannon made 10 muffins how many more did Laila make?

sleet_krkn [62]

Answer:

2 more muffins

Step-by-step explanation:

Since,

Given that:

Laila made 12 Muffins

Shannon made 10 Muffins

Question to Answer:
How many more did Laila make?

Solve:

Since it asking how many more laila made that means we have to subtract to find how many more laila has.

As given, we know that Laila made 12 Muffins and Shannon made 10 Muffins then:

Laila Muffins - Shannon Muffins

Which also means:

12 - 10

Which,

12 - 10 = 2

Hence, Laila makes 2 more Muffins than Shannon

What are the restrictions for a? 2a^2+a-15/5a^2+16a+3

koban [17]

ANSWER

The restrictions are

$a\ne -3,a\ne -\frac{1}{5}$

EXPLANATION

We were given the rational function,

$\frac{2a^2+a-15}{5a^2+16a+3}$

The function is defined for all values of a, except

$5a^2+16a+3=0$

This has become a quadratic trinomial, so we need to split the middle term.

We do that by multiplying the coefficient of $x^2$ which is 5 by the constant term which is 3. This gives us 15.

The factors of 15 that adds up to 16 are 1 and 15.

We use these factors to split the middle term.

$5a^2+15a+a+3=0$

We now factor to get,

$5a(a+3)+1(a+3)=0$

We factor further to get,

$(a+3)(5a+1)=0$

This implies that,

$(a+3)=0,(5a+1)=0$

This gives

$a=-3,a=-\frac{1}{5}$

These are the restrictions.
