The angle measurements in the diagram are represented by the following expressions

KIM [24]

Answer:

x = 12

∠A = 144

Step-by-step explanation:

+ We have: ∠A = ∠C (alternate interior)

∠D = ∠C ( vertically opposite angles)

=> ∠A = ∠C (because = ∠C)

=> 10x + 24 = 6x + 72

=> 10x - 6x = 72 - 24

4x = 48

x = 12

+ ∠A = 10x + 24

∠A = 10 x 12 + 24

∠A = 144

Please help me understand this number sequence

scZoUnD [109]

Answer:

Step-by-step explanation:

A=a(r)^t

a=1

time=2.5 hours=25/10 ×60=150 minutes

10t=150

t=150/10=15

$A=1(2)^{15}=32,768$

If the area rectangle below us 39 square feet find the x value

Leya [2.2K]

Answer:

x=5 and x=-11

Step-by-step explanation:

(x-2)(x+8)=39

$x^2+6x-16=39$

Subtract 39 from both sides

$x^2+6x-55=0$

Factor:

(x-5)(x+11)=0

Set factors to 0.

x-5 =0

x+11 =0

x=5, x=-11

For what values of the variable are the following expressions defined?

Rom4ik [11]

Answer:

The Expression will be defined if the denominator is not equal to 0 since any number divided by 0 is undefined.
Therfore our main priority here is to check the denominator only because it's the only part that can make the expression undefined
the expression will be defined for all real numbers (a) BUT 3+a must not equal to 0 therfore (a) can be all real numbers but must never be equal to -3

Step-by-step explanation:

$a \: is \: an \: element \: of \: all \: real \: numbers \: but \: not \: not \: equal \: to \: -3$

Which lines would be parallel, if any?

zimovet [89]

Line a can be rewritten as
.. 2y -x = 12
The coefficients of y and x match those of line b, so lines "a" and "b" are parallel.
