Brayden will take 10 tests in 5weeks how many test will he take in 7 weeks

14 tests

Step-by-step explanation:

For this question, we want to find the unit rate.

To do this, we must divide 10 by 5

10/5 = 2

So, that means that he takes 2 tests per week.

If he takes 2 tests per week, How many will he take in 7 weeks?

since 2 tests = 1 week, we can find out 7 weeks by multiplying each side by 7.

2*7 = 1 *7

2 * 7 = 14

1 * 7 = 7

14 tests = 7 weeks

So, in 7 weeks, he will take 14 tests.

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
