What is the solution to the equation -√(15+x)=-3?

2 answers:

7 0

So, the negative would be divided out to make it 3, then square both sides to get rid of the square root and get 9, then subtract 15 and you get -6.

X=-6

----------------
Plug in -6 for x
√15+(-6) = 3
Simplify
√9 = 3
Solution is x=-6

What is the area of this triangle?

Diano4ka-milaya [45]

ANSWER

56.1 square inches.

EXPLANATION

The area of this triangle can be calculated using the formula,

$Area = \frac{1}{2} ab \sin( C)$

where a=8in.

b=14.2 in.

and C=99° is the included angle.

We plug in these values to obtain,

$Area = \frac{1}{2} \times 8 \times 14.2 \sin( 99 \degree)$

$Area = 56.1007$

We round to the nearest tenth to get,

56.1 sq. inch

What is the gradient of the straight line 2y = -3x - 8 ?

lions [1.4K]

Answer:

- $\frac{3}{2}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope (gradient) and c the y- intercept )

Given

2y = - 3x - 8 ( divide all terms by 2 )

y = - $\frac{3}{2}$ x - 4 ← in slope- intercept form

with gradient = - $\frac{3}{2}$

A=. B= 2.6 c=6.2 using Pythagorean Theron what is a?

Kryger [21]

Hello!
So you will use the Pythagorean Theron equation which is Asquare + bsquare=C square
Plug in what you are given to find the missing piece

A square+ (2.6)square= (6.2) square
Asquare+ 6.76= 38.44
(Subtract 6.76to both sides to isolate A)
Asquare= 31.68
(Take the square root of both sides to find out what A is)
A=5.628
