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

My base is 10. My exponent is an odd number. If you write a multiplication sentence to show my value, it will have fewer than 4
svet-max [94.6K]
. The number is either 10^1 or 10^3 or 10^ 5 or . . . . 

<span>If it is more than 10, then it is not 10^1. The next possibility is 10^3which is 1000, which has factors 2, 5, 10, 20, 25, 40, 50, 80, . . . . . </span>

<span>What constitutes a "multiplication sentence" exactly ? This is not a standard mathematical term. Do you mean "reduce it to its prime factors" ? </span>

<span>1000 = 2 x 2 x 2 x 5 x 5 x 5 </span>

<span>which is a lot more than 4 factors. Or not, if you write it as 2³ x 5³. </span>

<span>But you could say the same about 100 000 = 2^5 x 5^5 </span>

<span>or about 10 000 000 = 2^7 x 5^7 </span>

<span>Take your pick. This is a very badly stated question. </span>

son4ous [18]

Answer:

Circle requires ≈ 20 m of edging

Step-by-step explanation:

A = πR²

R = √(A/π)

C = 2πR = 2π√(A/π)

C = 2π√(30/π) = 19.41625... ≈ 20 m

square needs ≈ 22 m of edging

equilateral triangle needs ≈ 25 m of edging
