y = 3x-2x∧2+5x∧3

When we replace x with value 3 we get

y = 3 * 3 - 2 * 3∧2 + 5 * 3∧3 => y = 9-2*9+5*27 => y = 9-18+135 => y = 126

good luck!!!

0.2x + (-0.9) + 1.7 = 9.6<br> 0.2x + 0.8 = 9.6
user100 [1]

Answer:44

Step-by-step explanation:

0.2x+(-0.9)+1.7==9.6

0.2x+0.8=9.6

Subtract 0.8 from both sides

0.2x+0.8-0.8=9.6-0.8

0.2x=8.8

Divide both sides by 0.2

0.2x ➗ 0.2=8.8 ➗ 0.2

x=44

Find the area of the figure:  Select one: a. 59.5 yd^2 b. 81 yd^2 c. 58.5 yd^2 d. 55.3 yd^2
lions [1.4K]
Answer would be 58.5 yd^2 .

You should take the base of the triangle multiplied by the height.

Formula: 1/2×base×height

In this case, you know that base is 13yd and height is 9 yd.

So, apply the formula.

Area = 1/2(13yd)(9yd) = 58.5 yd^2

*Do not include the " invisible length as it is not part of the actual triangle.

*Do not include 32yd as it is a hypotenuse and not a base. Hypotenuse is a side that is opposite a right angle triangle.

60 is 5/6 of what number?
Stels [109]
If x = the number you are trying to find:
60 =  \frac{5}{6}  * x
\frac{60}{ \frac{5}{6} }  = x
and when dividing by a fraction you can flip it and multiply instead:
60 * 6/5 = 72
The number is 72

There are no statements on your list that describe the roots.

If the discriminant is a negative number, then the two roots
of the equation are complex conjugates.  They both have
imaginary parts to them.
