If in the question it is 7x^2 and 3x^2, then

7x^2 - 4x + 10 + 3x^2 - 8

Re grouping the variables,

7x^2 + 3x^2 - 4x + 10 - 8

10x^2 - 4x + 2

The above would be the answer if the question was 7x^2 - 4x +10 +3x^2 - 8

Solve for x
Mademuasel [1]

Answer:

x = 9

Step-by-step explanation:

Using the rule of exponents

a^{m} × a^{n} ⇔ a^{(m+n)}

Given

11^{x} = 11^{4} × 11^{5} = 11^{(4+5)} = 11^{9}

Since the bases on both sides are common, then equate the exponents

x = 9
