Triangle, sum of all 3 angles = 180

so 180 - (99 + 11) = 180 - 110 = 70

answer: the third angle = 70

Yakvenalex [24]

Answer:

the number of miles run on Thursday is 5.60 miles

Step-by-step explanation:

The computation of the number of miles run on Thursday is shown below

Here we assume the number of miles be x

3 ÷ 4 ÷ 1 = 4.2 ÷ x

3 ÷ 4 ÷ x = 4.2

3x = 16.8

x = 5.6

Hence, the number of miles run on Thursday is 5.60 miles

We have the following expression given:

$(4y^3+28y^2)+(y+7)$

We can start selecting as common factor 4y^2 and we got:

$4y^2(y+7)+(y+7)$

Now we can select y+7 as common factor and we got:

$(y+7)\left\lbrack 4y^2+1\right\rbrack$

So then our final answer would be:

$(y+7)(4y^2+1)$
