8x² + 5 = 35
8x² = 35 - 5
8x² = 30
x² = 30/8
x² = 3.75
x = ±1.94  <span>to the nearest hundredth
</span><span>
So x</span>₁ = -1.94 and x₂ = 1.94

X=1.94
this is the answer because you subtract the 5 on both sides then divide by 8 which would be x^2=3.75, finally take the square root of both sides to get x=1.94 after rounding

Caleb is putting tile down in his bathroom and needs to know the perimeter of the floor. Two sides rectangular floor are 5 1/3 f
ladessa [460]

Answer:

  20 1/6 ft

Step-by-step explanation:

The perimeter is the sum of the lengths of the sides:

  2×(5 1/3 ft) + 2×(4 3/4 ft) = 10 2/3 ft + 8 6/4 ft

  = 10 2/3 ft + 9 2/4 ft . . . . change 6/4 ft to 1 1/2 ft

  = 10 8/12 ft + 9 6/12 ft = 19 14/12 ft  . . . . . use common denominator of 1/12 ft

  = 20 2/12 ft . . . . . . change 14/12 ft to 1 2/12 ft; next reduce that fraction

  = 20 1/6 ft . . . . perimeter of Caleb's bathroom

What are the zeroes of P(x) = x3 – 6x2 - x +62​
Maurinko [17]

Answer:

x = 6

x = -1

x = 1

Step-by-step explanation:

Given:

Correct equation;

P(x) = x³ - 6x² - x + 6

Computation:

x³ - 6x² - x + 6

x²(x-6)-1(x-6)

(x-6)(x²-1)

we know that;

a²-b² = (a+b)(a-b)

So,

(x-6)(x²-1)

(x-6)(x+1)(x-1)

So,

zeroes are;

x = 6

x = -1

x = 1

-5x + 4 = 2x + 16<br> How do I solve this
Cloud [144]
Subtract 2x from both sides then you’d have -7x+4=16 Then you subtract 4 from both sides and you’d get -7x=12. Next you divide both side by -7 so x=1.75 rounded to the nearest hundredth.

Pls help with this problem
madam [21]

Step-by-step explanation:

every triangle inscribed into a circle with the baseline being a diameter of the circle must be a right-angled triangle.

therefore,

angle XVY = 90°.

for VY we can use Pythagoras

c² = a² + b²

with c being the Hypotenuse (the line opposite of the 90° angle, in our case XY).

XY = 2×ZY = 2×17 = 34.

so,

34² = 30² + VY²

VY² = 34² - 30² = 1156 - 900 = 256

VY = 16
