Answer: -8

Explanation: so f(g(-1)) basically means f of g of -1. so we plug in -1 for x in g(x) and that equals 2(-1) + 5. so g(x) = 3. now we have f(3) because it’s f(g(-1)). f(3) = 1 - 3^2, which equals -8.

hope this helps!

Factor completely x^2 - 10x + 24

sergejj [24]

Hello.

The answer is: (x−4)(x−6)

Factoring means we want something like

(x+_)(x+_)

We need two numbers that...

Add together to get -10

Multiply together to get 24

Try -4 and -6:

-4+-6 = -10

-4*-6 = 24

Fill in the blanks in

(x+_)(x+_)

with -4 and -6 to get...

(x-4)(x-6)

Have a nice day

The expression 1/2bh gives the area of a triangle where b is the base of the triangle and h is the height of the triangle. What

iren [92.7K]

Hey there!

Let's plug these values into the formula.

1/2(7(4))

1/2(28)

Therefore, our area would be 14 sq cm.

I hope this helps!

Answer:

180

Step-by-step explanation:

From basic rules of a triangle we know that the interior angles of a triangle have to add up to equal 180°

But here is a formula for future references for finding the sum of the interior angles

interior angle sum = (n-2)180

where n = number of sides

and here is an example:

a triangle has 3 sides so we plug in 3 for n

(3-2)180

3-2=1

1*180 = 180

so the interior angles add up to equal 180

In parallelogram RSWY, find m

LuckyWell [14K]

Answer:

Part A) $m\angle R=110^o$

Part B) $m\angle S=70^o$

Step-by-step explanation:

we know that

In a parallelogram, opposite angles are congruent and consecutive angles are supplementary

step 1

Find the value of x

we know that

$m\angle R=m\angle W$ ----> by definition of parallelogram (opposite angles are congruent)

substitute the given values

$(5x-90)^o=(2x+30)^o$

solve for x

$5x-2x=30+90\\3x=120\\x=40^o$

step 2

Find the measure of angle R

$m\angle R=(5x-90)^o$

substitute the value of x

$m\angle R=(5(40)-90)=110^o$

step 3

Find the measure of angle S

we know that

$m\angle R+m\angle S=180^o$ ---> by definition of parallelogram (consecutive angles are supplementary)

we have

$m\angle R=110^o$

substitute

$110^o+m\angle S=180^o$

$m\angle S=180^o-110^o$

$m\angle S=70^o$
