Answer:

5) x = 8

6) z = 49°

Step-by-step explanation:

Hi there !

5)

we have opposite angles =>

5x = 2x + 24

5x - 2x = 24

3x = 24

x = 24 : 3

x = 8

6)

The sum of the three interior angles in a triangle is always 180° !

x = 180° - (28° + 39°)

= 180° - 67°

= 113°

x ; y = supplementary angles =>

x + y = 180° =>

y = 180° - x

= 180° - 113°

= 67°

z = 180° - (64° + 67°)

= 180° - 131°

= 49°

Good luck !

Find the area of the surface of the part of y=4x+z^2 that lies between the planes

adelina 88 [10]

Y) Recorder $4x$ and $z^2$

$y=z^2+4x$

X)Solve for $x$ by simplifying both sides of the equation, then isolate the variable

$x=- \frac{ z^{2} }{4}+ \frac{y}{4}$

Z)Take the root of both sides and solve.

$z= \sqrt{-4x+y}, - \sqrt{-4x+y}$

PART A. Expand the polynomial (x2 − y2)2 + (2xy)2, then simplify it by combining like terms.

sweet-ann [11.9K]

(x2-y1)²+(2xy)1 =
x⁴-2x²y²+y⁴+4x²y² =
x⁴+2x²y²+y⁴=
(x²+y²)²

! H E L P ! I have no idea, could you please answer them all I’d appreciate it.

The constant of proportionality is 5

For the first bar day: 1 cell phone sold: 5 (unit rate:5)

second bar day: 2 cell phones sold: 10 (unit rate:5)

third bar Day: 3 cell phones sold: 15 (unit rate: 5)

fourth bar day: 4 cell phones sold: 20 (unit rate 5)

Basically you divide the cell phones sold by the day or $\frac{rise}{run}$

Hope this helped <3
