Rasek [7]

Answer:

8

Step-by-step explanation:

Notice:

32 = (8 x 4)

72 = (8 x 9)

Hence,

32 + 72

= (8 x 4) + (8 x 9)       (factorize out the 8)

The sum of two numbers is -26. One number is 148 less than the other. Find the numbers
maks197457 [2]

Answer:

61 and -87

Step-by-step explanation:

If the numbers are x and x - 148, we can write the following equation:

x + x - 148 = -26

2x - 148 = -26

2x = 122

x = 61 so x - 148 = 61 - 148 = -87

] Complete the explanation of how you know whether the triangles are similar. If possible, find the Indicated length. A P 2.0 1.
disa [49]

1. The two triangles are similar because the two pairs of angles are equal, therefore the third angles of both triangles must also be equal.

We can call this the AAA similarity criterion

2. To find QR, we must use ratios between 2 known similar sides of both triangles,

\frac{2.0}{1.7}=\frac{1.2}{QR}\text{  , QR=}\frac{1.2\times1.7}{2.0}=\text{ 1.02}

So, QR =1.02
