Answer:
4x2 + 23x – 72
= (4x - 9)(x+8)
Step-by-step explanation:
hello :)
so let me just give you the answer first:
2/3 * d = 32 2/3
here is why
so since the sentence said 2/3 PER day, then d (the number of days) multiplied by the time spent each day playing piano should give you how much time was spent in total over the certian number of days.
the 32 2/3 is just the amount of time ellie spent (as you have said)
so, this equation would be the correct one.
i hope this helped you out! please vote me for brainliest and have splendid day!
Answer:
Step-by-step explanation:
The diagonals of a rhombus are perpendicular to each other, so angles (2) and (3) are equal 90°.
To find angle (1), we can use the sum of internal angles in the left triangle with angles 52°, (1), and (2):
The diagonals of a rhombus bisects the angles, to the angle next to the angle of 52° is also 52°, then, in the upper triangle, we have:
Answer:
x=10
Step-by-step explanation:
so your given an angle, 110, and another with an equation, 8x+30, which happens to be vertical to 110 degree angle meaning they are equal, so they both are equal to 110 now how do you solve for x? you simply reverse the equation that x is in, so you subtract 110-30=80, then divide by 8 giving you 10, so x=10.
It would be 120.
Look at the first column, 40. It’s basically multiplication and you can just use a calculator.
For example, 40 x 1 = 40,
And if you looks the second column, it’s being multiplied by 2. Which would be 40 x 2, you just have to multiply 3 x 40 which is 120.
Sorry for my english
