The like terms include 13b and 2b and when you combine them you get 15b. 3 and -4 are also like terms and when you combine them you get -1. b^2 doesnt have any like terms so its the same. The final answer is b^2+15b-1

Answer:

110687192.78951, 6488.47368421, 4214, 0.0464, 0.03626

SIMPLIFIED WAY OF SAYING IT:

Last One to First Box

3rd One to 2nd Box

1st one to 3rd box

2nd one to 4th box

4th one to 5th box

Step-by-step explanation:

(4.3*10^(6))*(9.8*10^(-4)) = 4,214

(2.9*10^7)*(1.6*10^-9) = 0.0464

(4.7*10^3)*(8.6*10^-7)/(3.8*10^-4)*(6.1*10^2) = 6488.47368421

(4.9*10^3)*(7.4*10^-6) = 0.03626

Last one = 110687192.78951

abcd is an isosceles trapezoid with legs ab and cd and base bc if the length of ab =-3y+54 the leingth of bc =5y+2 and the leing

Vilka [71]

ANSWER

$y = 5$

EXPLANATION

The given isosceles tra-pezoid has legs

$ab = - 3y + 54$

and

$cd = 6y + 9$

The base is bc=5y+2.

The length of the legs of the isosceles tra-pezoid are equal.

This implies that,

$ab = cd$

Thus,

$- 3y + 54 = 6y + 9$

Group similar terms,

$54 - 9 = 6y + 3y$

$45 = 9y$

Divide both sides by 9.

$y = \frac{45}{9}$

$y = 5$

40=3x+x^2<br><br> How do I find the answer to this

tamaranim1 [39]

Answer:

x = -8, x = 5

Step-by-step explanation:

This can be solved using Factorization method:

$40 = 3x + {x}^{2} \\ \\ \implies \: {x}^{2} + 3x - 40 = 0 \\ \\ \implies \: {x}^{2} + 8x - 5x- 40 = 0 \\ \\ \implies \: x({x} + 8) - 5(x + 8) = 0 \\ \\ \implies \: ({x} + 8) (x - 5) = 0 \\ \\ \implies \: ({x} + 8) = 0 \: \: or \: \: (x - 5) = 0 \\ \\ \implies \: x = - 8 \: \: or \: \: x = 5 \\ \\ x = - 8, \: \: 5$
