Answer:
The answer is 1st point
Step-by-step explanation:
(12x²+4x-5)-(9x²-9x+1)
= 12x²+4x-5-9x²+9x-1
= 3x²+13x-6
Answer:
£59.25
Step-by-step explanation:
17²-8²=225
√225=15
1/2(12+20)×15=240m²
240÷100=2.4
3×19.75=£59.25
Answer:
-80
Step-by-step explanation:
Subtract 4:
-10 = x/8
Multiply by 8:
-80 = x
The value of x is -80.

This sort of equation is sometimes referred to as a "two-step" linear equation.
<u>Step 1</u>. After you identify the term containing the variable (x/8), you identify any constants on the same side of the equal sign (+4). Add their opposite to both sides of the equation. That gets the variable term by itself.
<u>Step 2</u>. Then identify the coefficient of the variable (1/8). Multiply both sides of the equation by the reciprocal of this value. That will make the coefficient of the variable become 1. The constant on the other side of the equal sign is now the value of the variable.
