Which number is a zero of the given function? g(x) = (x^2– 36) (x + 7)

1 answer:

4 0

You can factor it more
Remember: (a^2 - b^2) = (a-b)(a+b)
(x^2 - 36) = (x - 6)(x + 6)
Now plug back to equation

(x - 6)(x + 6)(x + 7) = 0
x - 6 = 0, x = 6
x + 6 = 0, x = -6
x + 7 = 0, x = -7

Solution: x = 6, -6, -7

P=3y/q solve for y make sure to add steps pls

Likurg_2 [28]

Answer:

Solving for y gives:

$y = \frac{pq}{3}$

Step-by-step explanation:

Linear equations are the equations that are degree one equations. When it is asked to solve an equation for a specific variable that means that the specified variable has to be isolated on one side of the equation i.e. in the given question solving for y means isolating y on one side of the equation.

Given equation is:

$p = \frac{3y}{q}$

Multiplication property of equality(Multiplying both sides by q)

$p*q = \frac{3y}{q} * q\\pq = 3y$

Division property of equality(Dividing both sides by 3)

$\frac{pq}{3} = \frac{3y}{3}\\\frac{pq}{3} = y$

Hence,

Solving for y gives:

$y = \frac{pq}{3}$

If someone helps me I’ll give brainless

Sunny_sXe [5.5K]

Answer:

128

Step-by-step explanation:

The two angles form a straight line so they add to 180

2m+62 + 3m +143 = 180

Combine like terms

5m+205=180

Subtract 205 from each side

5m+205-205=180-205

5m = -25

Divide by 5

5m/5 = -25/5

m = -5

We want to find the angle so we substitute the value of m into the the formula for the angle.

< RBM =3m +143 = 3(-5) +143 = -15+143 =128

Find angle B if triangle ABC below is isosceles.

butalik [34]

The two base angles of an isoceles triangle are equal so we can conclude that

2x - 20 = x + 8

Now we just need to solve for x:

2x - 20 + 20 = x + 8 + 20

2x = x + 28

2x - x = x + 28 - x

x = 28

So, angle B = x + 8 which is 28 + 8 = 36°
