(X+4)(x+7) what’s the problem

X^2+11x+28

Step-by-step explanation:

FOIL = First, Outer, Inner, Last

First: x times x= x^2

Outer: x times 7= 7x

Inner: 4 times x= 4x

Last: 4 times 7= 28

Since outer and inner are both positive you would add togther. Therefore answer is x^2+11x+28

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
