Prove that if -5(x + 4) = 70, the x = -18. Write a justification for each step.

crimeas [40]

Step-by-step explanation:

Let's solve your equation step-by-step.

−5(x+4)=70

Step 1: Simplify both sides of the equation.

−5(x+4)=70

(−5)(x)+(−5)(4)=70(Distribute)

−5x+−20=70

−5x−20=70

Step 2: Add 20 to both sides.

−5x−20+20=70+20

−5x=90

Step 3: Divide both sides by -5.

−5x

−5

x=−18

Answer:

21mm

Step-by-step explanation:

The formula for solving the area of a rhombus is : $\frac{1}{2}xy$ , where x and y are two intersecting diagonals.

In this case, we are given both values, thankfully. 6 and 7 are to be replaced with x & y. Now, the rest you have to do is simple math.

$(6 * 7) / 2 = 21$

The area of the rhombus is 21mm.
