Okay thanks

Step-by-step explanation:

s=t+5
4s+2t=110
pls help me

Answers

Answer:

t = 40/3 (exact)

t = 13.3 (decimal)

t = 13 1/3 (mixed number)

Step-by-step explanation:

Simplify 4 (t + 5) + 2 (t + 5).

6t + 30 = 110

Move all terms not containing t to the right side of the equation.

6t = 80

Divide each term by 6 and simplify.

t = 40/3

The result can be shown in multiple forms.

t = 40/3 (exact)

t = 13.3 (decimal)

t = 13 1/3 (mixed number)

Answer:

s=20

Step-by-step explanation:

First, plug in s to the equation.

4(t+5) + 2t =110

Then, distribute. That means multiply 4 to the variable and number inside the parentheses.

4t + 20 +2t = 110

Now, add like terms. The two numbers, 4t and 2t can be combined because they have the same variable.

6t + 20 = 110

Subtract 20 from 110 to isolate the variable.

6t = 90

Now, divide 90 by 6 to further isolate the variable.

t = 15

Now we have to find s. To find s, plug t = 15 into the equation.

s = 15 + 5

Lastly, add the two numbers to find s.

s = 20

Check your work! Plug in t = 15 and s = 20 to the equation.

4(20) + 2(15) = 110

Multiply.

80 + 30 = 110

110 = 110

This means your answers are correct! Hope this helped! :)

PLS HELP AND IF YOU COULD SHOW UR WORK IT WOULD HELP A LOT <33

Answers

So if you want to have a factored form...

If the zeroes are +4 and +8, you would write
(X-4) (x-8)
Then you would multiply it out to get to quadratic form...

So, (x-4)*(x-8)
X^2 - 12x + 32

Then you would plug it into the formula for axis of symmetry...
X= -b/2a

X=12/2 = 6


X=6

Answers

Answer:

Trapezoid

Step-by-step

The given shape in the image is a trapezoid. The correct option is D.

What is a trapezoid?

A trapezoid (also known as a trapezium in some countries) is a quadrilateral with at least one pair of parallel sides. The parallel sides are called the bases, and the other two sides are called the legs. The height of a trapezoid is the perpendicular distance between the bases.

The formula for the area of a trapezoid is:

A = (a + b) x h / 2

Where A is the area, a and b are the lengths of the two bases, and h is the height (or altitude) of the trapezoid.

Trapezoids can be either right or oblique, depending on the angle between the bases. In a right trapezoid, one of the angles between the legs and the base is a right angle (90 degrees). In an oblique trapezoid, none of the angles between the legs and the base is a right angle.
