Solve this −14(z−5)=−14z+70

All real numbers are solutions.

Explanation:

−14(z − 5) = −14z + 70

[ Step 1: Simplify both sides of the equation ]

−14(z − 5) = −14z + 70

(−14)(z) + (−14)(−5) = −14z + 70 (Distribute)

−14z + 70 = −14z + 70

[ Step 2: Add 14z to both sides ]

−14z + 70 + 14z = −14z + 70 + 14z

70 = 70

[ Step 3: Subtract 70 from both sides ]

70 − 70 = 70 − 70

0 = 0

Therefore, all real numbers are solutions.

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
