Answer:
Step-by-step explanation:
1) the triangle is right, so we can use the Pythagorean theorem
x^2 + 24^2 = (16+x)^2
x^2 + 576 = x^2 + 256 + 32x
32x = 320
x = 10
2) the two segment are congruent, so
7x - 13 = 9x - 23
2x = 10
x = 5
D. Pyramid volume is calculated 1/3×base area×height
You would multiply the amount by 1.70 for example increasing £50 by 70% would be £85
<u><em>Answer:</em></u>
The missing term is 3x²
<u><em>Explanation:</em></u>
Addition and subtraction can only take place between like terms.
<u>For two terms to be like</u>, both the variable and its degree must be the same in both terms
<u>Now, consider the given terms:</u>
First term is 7x² has the variable x with degree 2
The resulting term is 10x² has the variable x with degree 2
This means that the missing term is ax²
We need to get the value of "a"
<u>This is done as follows:</u>
ax² + 7x² = 10x²
x²(a+7) = 10x²
a+7 = 10
a = 10-7
a = 3
Therefore, the missing term is 3x²
