4 0
STEP-BY-STEP SOLUTION:

0 = ( 5x + 13 ) ( 3x + 7 )

0 = 15x^2 + 35x + 39x + 91

0 = 5x ( 3x + 7 ) + 13 ( 3x + 7 )

0 = ( 3x + 7 ) ( 5x + 13 )


3x + 7 = 0

3x = - 7

x = - 7 / 3


5x + 13 = 0

5x = - 13

x = - 13 / 5


ANSWER:

Therefore, there are two solutions to this problem. The answer is:

x = - 7 / 3

&

x = - 13 / 5

Not sure about the weird echo in the question but I think we're being ask to evaluate

4 - 0.25g + 0.5h

when g=10, h=5

That's

4 - 0.25(10) + 0.5(5) = 4 - 2.5 + 2.5 = 4

Answer: 4

because the angles in a rectangle are 90 degrees it is not a parallelogram true or false? please explain why
ra1l [238]
<span>A parallelogram is a 4-sided shape where opposites sides are parallel. A rectangle is a special case of a parallelogram. All rectangles are parallelograms.

But a rectangle is a shape where opposites sides are parallel *and* all the corners are 90 degree angles. So you can't say that all parallelograms would be rectangles. Some parallelograms would be rectangles, but not all.

Rectangles are a subset of the shapes called parallelograms. But parallelograms are *not* a subset of the shapes called rectangles.

It's similar to saying all cars are vehicles. But you can't say that all vehicles are cars. </span>

Llana [10]

Answer:

11 pizzas, 5/7 left

Step-by-step explanation:

to find out how much pizza is needed, multiply 4/7 by 18 to get 72/7. round up to get 77/7 or 11 pizzas. 77/7 - 72/7= 5/7 so there will be 5/7 left over
