Answer:

→ [2 × 24/3] + 7

Divide 24 by 3 we get 8 as the product:

→ [2 × 8] + 7

Now, multiply 8 by 2 we get product as 16 :

→ 16 + 7

Let's add the 16 and 7 and we get final answer as :

→ 23

What’s the distance between (4,-9) and (5,3)

laila [671]

Answer: Distance = √145

Concept:

Here, we need to know the concept of the distance formula.

The distance formula is the formula, which is used to find the distance between any two points.

If you are still confused, please refer to the attachment below for a clear version of the formula.

Solve:

Given information

(x₁, y₁) = (4, -9)

(x₂, y₂) = (5, 3)

Given formula

$Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Substitute values into the formula

$Distance = \sqrt{(5-4)^2+(3+9)^2}$

Simplify values in the parentheses

$Distance = \sqrt{(1)^2+(12)^2}$

Simplify exponents

$Distance = \sqrt{1+144}$

Simplify by addition

$Distance = \sqrt{145}$

Hope this helps!! :)

Use the quadratic formula to solve the equation. -2x^2-x+7=0.

Furkat [3]

-2x^2-x+7=0
Variable with the highest degree's (exponent) constant, -2 is a, next variable's constant, -1 is b, the constant or number without a variable, 7 is c

using substitution put the numbers into the formula
(-b±√(b^(2)-4ac))/(a^(2))

(-(-1)±√((-1)^(2)-4(-2)(7))/((-2)^(2)) simplify

(1±√(1+56))/4

1±√(57)/4 is your answer
