Answer: 9
Step-by-step explanation: Here, we have the expression <em>4x - 7</em> and we want to evaluate the expression when <em>x</em> is equal to 4.
To evaluate an expression, we simply plug the value
of the variable into the expression and solve.
So here, since <em>x</em> is equal to 4, we have 4(4) - 7.
4(4) is equal to 16.
So we have 16 - 7 which is equal to 9.
So the value of our expression when <em>x</em> is equal to 4 is 9.
Answer:
976 cm^2.
Step-by-step explanation:
The surface area = 2 * area of the triangular side + 2 * area of the rectangular sides + area of the rectangular base.
= 2 + 1/2 * 24 * 14 + 2 * 25 * 10 + 14*10
= 336 + 500 + 140
= 976 cm^2.
