How to solve -7-8(6x+5)

koban [17]

Answer: -47 - 48x

Step-by-step explanation: When you first take a look at this problem, it's tempting to want to subtract -7 - 8 to get -15 and then distribute the -15 through the parentheses.

You wouldn't want to subtract however before you distribute because the distributive property is a form of multiplication and remember from your order of operations that multiplication comes before subtraction.

So the first thing you want to do here is distribute and change the minus sign in front of the -8 to plus a negative 8 so that you know you are distributing a -8 through your parentheses.

So we have -7 + -8 times 6x which is -42x + -8 times 5 which is -40.

Now we have -7 + -48x + -40.

Now just combine your like terms. -7 + -40 is -47 and plus a negative 48x can be written as -48x so we have -47 - 48x.

So your answer is just -47 - 48x.

consider a quadrilateral with vertices d(0,0), i(5,5) n(8,4) g(7,1). determine the most accurate type of quadrilateral from the

Burka [1]

Answer:

Plotting the points into the coordinate plane gives us an observation that this quadrilateral with vertices d(0,0), i(5,5) n(8,4) g(7,1) is a KITE, as shown in figure a.

Step-by-step explanation:

Considering the quadrilateral with vertices

d(0,0)

i(5,5)

n(8,4)

g(7,1)

Plotting the points into the coordinate plane gives us an observation that this quadrilateral with vertices d(0,0), i(5,5) n(8,4) g(7,1) is a KITE, as shown in figure a.

From the figure a, it is clear that the quadrilateral has

Two pairs of sides
Each pair having two equal-length sides which are adjacent
The angles being equal where the two pairs meet
Diagonals as shown in dashed lines cross at right angles, and one of the diagonals does bisect the other - cuts equally in half

Please check the attached figure a.

Which numbers are greater than 0.7? 0.37, 0.9, 0.08, 0.69, 0.71

Marat540 [252]

<span>The correct ansswer is option B. i.e. 0.9 . Because 0.37 and 0.08 are clearly lesser. And amongst, 0.69, 0.71 and 0.9, the number 0.91 is the greatest of all. So, 0.91 is greater than 0.7 from all the given options.</span>
