Plz help me fast. I'll give 5 points

A parallelogram has two pairs of opposite equal angles.
ABCD so
A = C and B = D

A = 2x + 35
C = 3x - 5

2x + 35 = 3x - 5
35 + 5 = 3x - 2x
40 = x

A = (2 x 40) + 35 = 115
A = C = 115

Sum of angles of a quadrilateral = 360

Angles B and D are equal
So
B = (360 - (115 + 115))/ 2
= 130/2
= 65

B = D = 65

PLEASE PLEASE PLEASE PLEASE HELP ME NO ONE WANTS TO HELP

Answer:

You have to know the basic properties of exponents.

Jill's answer is wrong because you add the powers when there are like bases. You don't multiply.

$2^{-3} *2^{6} = 2^{3}$

-3+6=3

The base stays the same.

An open box is to be constructed so that the length of the base is 3 times larger than the width of the base. If the cost to con

natta225 [31]

Answer:

Step-by-step explanation:

Let assume that the volume = 88 cubic feet

Then:

$L = 3w --- (1)volume = l \times w \times h \\ \\ 88 = (3w) \times w \times h \\ \\ 3w^2 h= 88 \\ \\ h = \dfrac{88}{3w^2}--- (2) \\ \\$

The construction cost now is:

$C = 4(l \times w) + 2 ( w \times h) + 2(l \times h) \\ \\ C = 4(3w^2) + 2(w \times \dfrac{88}{3w^2}) + 2(3w \times \dfrac{88}{3w^2}) \\\\ C = 12w^2 + \dfrac{176}{3w} + \dfrac{176}{w}$

Now, to determine the minimum cost:

$\dfrac{dC}{dw}= 0 \\ \\ \implies 24 w - \dfrac{176}{3w^2}- \dfrac{176}{w^2}=0 \\ \\ 24 w ^3 = \dfrac{176}{w^2}(\dfrac{1}{3}+1) \\ \\ 24 w ^3 = \dfrac{176(4)}{3} \\ \\ w^3 = \dfrac{88}{3(3)}$

$w = \dfrac{88}{3(3)}^{1/3} \ feet$

Now;

$length = 3 ( \dfrac{88}{3(3)})^{1/3} \ feet$

$height = ( 88})^{1/3} (3)^{1/3} \ feet$

Evaluate 2n-1, where N -7

IceJOKER [234]

The value of the expression 2n - 1 when n = 7 is 13.

<h3>Equation</h3>

2n - 1

when n = 7

Substitute n = 7 into the equation

2n - 1

= 2(7) - 1

= 14 - 1

= 13

<h3>What is mathematical expression?</h3><h3 />

Mathematical expression is an expression which involves the combination of numbers and variables in a valid way, in a function of addition, subtraction, multiplication, division and exponentiation

Therefore, the value of the expression 2n - 1 when n = 7 is 13.
