<h3>3^2 × (-2)^3 × 5</h3><h3>= 9 × 8 × 5</h3><h3>= 72 × 5</h3><h3>= 360</h3>
Thank you ☺️☺️
(34 + 6 ) * 3
there would be no equal sign since it is an expression
X^2 + 16x + 61 = 0
x^2 + 16x = -61
x^2 + 16x + 64 = -61 + 64
(x + 8)^2 = 3
x + 8 = (+-) sqrt 3
x = -8 (+-) sqrt 3
x = -8 + sqrt 3...and x = -8 - sqrt 3 <== ur solutions
Answer:
the mean weight is 22 tonnes
Step-by-step explanation:
mean=total sum/number of numbers you added
in this case the question already gave you the total so just divide right away
mean weight= 330/15 = 22 tonnes
This makes a right triangle with hypotenuse x+2 and legs 10 and x
10²+x²=(x+2)²
100 + x² = x²+4x+4
100=4x+4
4x=96
x=24, the height we are looking for
