Number four?????????????????

ivolga24 [154]

Because the sum of the angles MRN and NRT equal angle MRT, the equation to solve for g would by 2g-2 + 4g -9 = 133

2g-2+4g-9 = 133
combine like terms

6g - 11 = 133
add 11 to both sides

6g = 122
divide both sides by 6

g=122
Now that you know what g is, you can plug it into the equation 2g -2 which would be 46

Which of the following product? assume y>0 3 square root(y^2 square root 4+ square root 8y)

Arada [10]

Answer:

$6y^2\sqrt{10}+12\sqrt{5y}$

Step-by-step explanation:

Use the distributive property and the rules for forming and simplifying square roots.

(√a)(√b) = √(ab)

√(a²b) = a√b

$3\sqrt{10}\cdot(y^2\sqrt{4}+\sqrt{8y})=(3\sqrt{10})(2y^2) +(3\sqrt{10})(\sqrt{8y})\\\\=6y^2\sqrt{10}+3\sqrt{80y}\\\\=6y^2\sqrt{10}+3\sqrt{(4^2)(5y)}\\\\=\boxed{6y^2\sqrt{10}+12\sqrt{5y}}\qquad\text{matches the first choice}$

Solve for x.<br> 3^2x= 15<br> (Type an integer or decimal rounded to the nearest tenth as needed.)

Lena [83]

Let's solve your equation step-by-step.

(3^2)(x)=15

Step 1: Simplify both sides of the equation.

9x=15

Step 2: Divide both sides by 9.

9x/9=15/9

x=5/3

Answer:

x=5/3
