Answer:
The solutions are x = -7, 6.
Step-by-step explanation:
To find the solutions, move everything to one side of the equation so the equation is equal to 0. Then factor. Set the factors equal to 0 and solve for x.
x+7 = 0
x = -7
and
x-6 = 0
x = 6
The solutions are x = -7, 6.
The answer is 63 units, just add them up.
Answer:
x = 60°
Step-by-step explanation:
This is an equilateral triangle. All angles of this triangle are congruent and have a measure of 60°.
Other method.
We know: the sum of the measures of the angles of the triangle is equal to 180 °.
Therefore we have the equation:
x + x + x = 180°
3x = 180° <em>divide both sides by 3</em>
x = 60°
The value of (26 - 7) and (5 - 24) when they're multiplied will be -399.
<h3>How to multiply the values?</h3>
From the information given, we are told to multiply (26 - 7) and (5 - 24). This goes thus:
= (26 - 7) × (5 - 24)
= 21 × -19
= -399
In this case, value of (26 - 7) and (5 - 24) when they're multiplied will be -399.
