Answer:

No, she's incorrect. You cannot split up something in parenthesis when it is being squared. By doing so she doesn't have a middle term. The correct equation is 25x^6 + 30x^3 + 9

Step-by-step explanation:

1. Square the first term.

(5x^3)^2 = 25x^6

2. Square the second term.

3^2 = 9

3. Multply the two terms together and multiply by two.

5x^3 × 3 = 15x^3

15x^3 × 2 = 30x^3

4. Add everything together.

25x^6 + 30x^3 + 9

I hope this helps!

Answer:

B. 25 ft

Step-by-step explanation:

We have the following points:

B- position of baby bird
M- position of momma bird
G- base of the tree

Given:

GM = 18 feet
BG = x
m∠BMG = 54°

Find the value of x:

x / GM = tan ∠BMG
x / 18 = tan 54°
x = 18 tan 54°
x = 24.77 ≈ 25 ft

Correct choice is B

garri49 [273]

Let's solve your equation step-by-step.0.2(x+50)−6=0.4(3x+20)Step 1: Simplify both sides of the equation.0.2(x+50)−6=0.4(3x+20)(0.2)(x)+(0.2)(50)+−6=(0.4)(3x)+(0.4)(20)(Distribute)0.2x+10+−6=1.2x+8(0.2x)+(10+−6)=1.2x+8(Combine Like Terms)0.2x+4=1.2x+80.2x+4=1.2x+8Step 2: Subtract 1.2x from both sides.0.2x+4−1.2x=1.2x+8−1.2x−1x+4=8Step 3: Subtract 4 from both sides.−1x+4−4=8−4−1x=4Step 4: Divide both sides by -1.−1x−1=4−1x=−4Answer:x=−4
