Prove that the two circles shown below are similar.

Step-by-step explanation:

The radius of Circle E is 3 units, while that of circle C is 4 units.  The circles have exactly the same shape.  If all radii of circle E were multiplied by 4/3, the resulting circle would exactly match Circle C.  That the circles have different centers is immaterial.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
