Help? what should i choose

Mathematics
1 answer:
igomit [66]3 years ago
8 0

Answer:

Step-by-step explanation:

Angles on a straight line add up to 180 so:

180-110 = 70

As this is an isosceles triangle,

y must be 70.

We know y is 70 and there are 2y and one x. A triangle also adds up to 180.

This means:

2y+x = 180

2(70)+x = 180

140+x = 180

x = 40

x = 40  y = 70

Find the equation of the line shown.
Luda [366]

Answer:

y = -x + 9

Step-by-step explanation:

✔️Find the slope using (9, 0) and (7, 2):

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 0}{7 - 9} = \frac{2}{-2} = -1

Slope (m) = -1

✔️Find the y-intercept (b):

The line intercepts the y-axis when y = 9. Therefore, y-intercept (b) = 9

✔️Substitute m = -1 and b = 9 into y = mx + b

Thus,

y = -1(x) + 9

y = -x + 9

What is 34 tens + 20 tens =
FromTheMoon [43]
34 tens + 20 tens = ?

1 ten = 10 ones or 10.

34 + 20 = 54
54 tens
34 tens + 20 tens = 54 tens 

54 × 10 = 540

34 tens + 20 tens = ?
34 tens + 20 tens = 54 tens
34 tens + 20 tens = 540

Can anyone help me?
Charra [1.4K]
                                                                    V = lwh
                                    2x³ + 17x² + 46x + 40 = l(x + 4)(x + 2)
                 2x³ + 12x² + 16x + 5x² + 30x + 40 = l(x + 4)(x + 2)
2x(x²) + 2x(6x) + 2x(8) + 5(x²) + 5(6x) + 5(8) = l(x + 4)(x + 2)
                     2x(x² + 6x + 8) + 5(x² + 6x + 8) = l(x + 4)(x + 2)
                                      (2x + 5)(x² + 6x + 8) = l(x + 2)(x + 4)
                              (2x + 5)(x² + 2x + 4x + 8) = l(x + 4)(x + 2)
                  (2x + 5)(x(x) + x(2) + 4(x) + 4(2)) = l(x + 4)(x + 2)
                          (2x + 5)(x(x + 2) + 4(x + 2)) = l(x + 4)(x + 2)
                                    (2x + 5)(x + 4)(x + 2) = l(x + 4)(x + 2)
                                          (x + 4)(x + 2)           (x + 4)(x + 2)
                                                           2x + 5 = l
