Answer:

Assuming you meant : -5(s-30)=10, then s = 28

Step-by-step explanation:

-5(s-30)=10

there are a coupe ways to solve, I will start by dividing the -5 on both sides

(-5(s-30))/-5 = 10/-5

=> s-30 = -2

Combine like terms:

(s-30)+30 = -2+30

s=28

ANSWER

A. 73

EXPLANATION

The given expression is

$(2{x})^{2} - 3{y}^{2}$

We substitute x=5 and y=3 to obtain:

$(2 \times 5)^{2} - 3{(3)}^{2} = {10}^{2} - 3 \times 9$

This simplifies to,

$= 100 - 27$

$= 73$

The correct choice is A.

Use a graphing calculator to sketch the graph of the quadratic equation, and then give the coordinates for the x-

Umnica [9.8K]

Given:

The quadratic equation is

$y=6x^2-15x+6$

To find:

The x-intercepts of the given equation.

Solution:

We have,

$y=6x^2-15x+6$

Splitting the middle term, we get

$y=6x^2-12x-3x+6$

$y=6x(x-2)-3(x-2)$

$y=(x-2)(6x-3)$

For x-intercepts, y=0.

$(x-2)(6x-3)=0$

Using zero product property, we get

$x-2=0\text{ and }6x-3=0$

$x=2\text{ and }6x=3$

$x=2\text{ and }x=\dfrac{3}{6}$

$x=2\text{ and }x=0.5$

So, the x-intercepts are (0.5,0) and (2,0).

Therefore, the correct option is a.

Can someone plz help me

Illusion [34]

First rectangle:
Has 3 cubes in each 5 layers, and imagine it, so we have all dimension needed which is:
l=3 unit
w=1 unit
h=5 unit.
V=l×w×h
V=3×1×5
V=15 cubic inches.

Second rectangular:
Doing the same like that to get:
l=5 unit
w=1 unit
h=3 unit
V=15 cubic inches. As a result, there are no prism that are greater to each other, which mean that they have the same volume of 15 cubic inches. Hope it help!
