Simplify the expression: -7d+5(10d+-6)
-7d+50d+-30= 43d+-30distributive property when there is parentheses and a number infront.combine like terms. only if they have the same variable.then just put them in an expression.
60 * 1/6 = 10
we can expect 10 times to roll the 2.
step-by-step explanation: if we assume that the triangle with points b' c' and a' is multiplied by 1.5 the answer would be 4 * 1.5 = 6
to get this we take b' (7.5) and divide it by b (5) to get 1.5
7.5/5 = 1.5; 4*1.5 = 6
