Solve to find the value of x.

Mathematics
1 answer:
Tresset [83]2 years ago
6 0

Answer:

x=12

Step-by-step explanation:

We know that a right angle is 90 degrees. So we can make the equation 35+4x+7=90. Now, we can solve fore X! We can combine 35 and 7 to make the equation 4x+42=90. In order to isolate x we have to subtract 42 from both sides, getting us the equation 4x=48. Now, in order to isolate x we must divide each side by 4, getting us the equation 12=x.  To prove that x=12, we can subsitute x for 12.  This means that we can do 35+4(12)+7=90. Or, 35+48+7 =90, which simplified, is 90=90, making x=12 true. Hope this helps :)

How to find the area of a sector with a sector angle of 72 degrees and a radius of 14 cm​
skad [1K]

Answer:

Exact area: 39.2π cm²

Approximate area: 123.2 cm²

Step-by-step explanation:

The area of a circle is πr².

A full circle can be thought of as a sector of a circle with 360° of central angle. For a sector of a circle with a central angle of n°, multiply the area of the circle by the fraction n°/360°.

The formula for the area of a sector of circle with central angle n° and radius r is

A = (n°)/(360°) × πr²

Here we have n = 72; r = 14 cm

A = (n°)/(360°) × πr²

A = (72°)/(360°) × π × (14 cm)²

A = 39.2π cm² = 123.2 cm²

AVprozaik [17]
Multiply the equation 2x+7y=-1 by -2

add to othe equaiton
4x-3y=-19
<u>-4x-14y=2 +</u>
0x-17y=-17

-17y=-17
divide both sides by -17
y=1

sub back
2x+7y=-1
2x+7(1)=-1
2x+7=-1
minus 7 from both sides
2x=-8
divide both sides by 2
x=-4

x=-4
y=1

Question 2
Oliga [24]

Answer:

9

Step-by-step explanation:

you want the trinomial (x*x - 6x + __ ) to be written as a binomial squared.

So we would need to realize that the constant would be equal to (-6/2)^2  =(-3)^2 = 9

We have completed the square.

f(x) = 4*( x - 3)^2  + 20   is now in Vertex Form
